Considering Jobs in the Homeland Security Field

leave a comment »

Who are Homeland Security professionals, and what do they do?  There’s a lot of diversity in Homeland Security jobs.  Some are at the federal level, mostly with the Department of Homeland Security (DHS), a federal department created in 2002 in response to the terror attacks of September 11, 2001.  According to DHS, the department’s overriding mission is to lead the unified national effort to secure our country and preserve our freedoms.

 The Department of Homeland Security has a vital mission: to secure the nation from the many threats we face. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analyst to chemical facility inspector. Our duties are wide-ranging, but our goal is clear – keeping America safe.  (http://www.dhs.gov/xabout/)

 

DHS is among the largest Federal agencies, because it was created by merging 22 existing departments and agencies which had a part of the overall Homeland Security mission.  If you’ve been through an airport lately, you’ll have seen DHS Transportation Security Agency officers on the job.  If you know someone who has applied to immigrate to the US or who has become a citizen, that person got assistance from a DHS Citizenship and Immigration officer.  DHS Border Patrol agents help keep smugglers from bringing people and goods into the country unlawfully.  If your community faced a serious disaster, like a major hurricane, DHS Federal Emergency Management officers were on the scene.  People who live along the coasts, or near major rivers and lakes, know that the US Coast Guard is there to secure the waterways and save lives.

Other DHS officers help local police and firefighters prepare for emergencies, including potential terrorist attacks, and some help companies and individuals protect their computer systems from attack.

Here are a few of the jobs DHS officers do:

  •  Customs and Border Protection
  •  Federal Emergency Management
  •  Transportation Security
  •  Coast Guard
  •  Secret Service
  • Counterterrorism
  • Cybersecurity Analysis

 

As you can see, Homeland  Security is a broad field which includes some very different kinds of work… but all in service of the same unified mission.  Choosing a Homeland Security career means taking a close look at your own strengths and interests, and at position requirements, to make sure you find a good fit.

Homeland Security jobs aren’t just at the Department of Homeland Security, though.  Most people in Homeland Security career fields work at the local level, as law enforcement officers, emergency management officials, security staff at private companies, utilities, or other facilities, and firefighters or emergency medical services technicians.

Let’s consider jobs in each of these three categories:

  •  First responders.  These are local officers who are the first at the scene when people need help.  They include police officers, firefighters, and emergency medical crews.
  •  Private sector security professionals.  These are essential, because over 85 percent of the nation’s critical infrastructure (meaning those buildings and facilities of the greatest importance to national security and economic survival) belongs to private owners, not to government.  Private owners and operators are the first line of defense for their own security, and they hire professional security staff to manage the job.
  •  Emergency management professionals.  Most local governments, like cities and counties, have an emergency management office to respond to disasters.  These include natural disasters like floods, fires, hurricanes, and earthquakes, and disasters created by human actions, like terrorist attacks or a crime endangering a large number of victims.  States also have emergency management agencies.  (The Federal Emergency Management Agency (FEMA), part of the Department of Homeland Security, handles this at the federal level.)   In addition to jobs with local governments, emergency management professionals also work for private-sector organizations which respond to crises, like the American Red Cross.

 

The Biodefense Network: Countering Biological, Chemical, and Radiological Threats Through Medical Research

leave a comment »

In the tradition of the Manhattan Project, which brought great scientific minds together in a successful effort to field an atomic bomb before the Nazis could do so, the US is building a research and development network aimed at countering chemical, biological, and radiological attacks.  The project is a public-private partnership, meaning that government funding from the U.S. Biomedical Advanced Research and Development Authority (part of the Department of Health and Human Services) is used to support research at private-sector institutions like Texas A&M University.

Homeland Security Newswire and the Associated Press both reported on the project during the week of 23 July 2012.  There will be five participating centers, with facilities in Texas, North Carolina, and Maryland.

According to the Associated Press, the Texas A&M center’s work will range from vaccine research to training medical professionals on Homeland Security threats like bioterrorism:

The center is tasked to use what A&M describes as “rapid, nimble and flexible approaches” to come up with vaccines against pandemic influenza; devise accelerated methods to develop those vaccines to licensure; develop therapies for chemical, biological, radiological and nuclear threats; and train “the next generation of professionals” to sustain the nation’s capability in those areas.

Officials showed off labs where research already is focused on cancer-fighting drugs and where students can learn how to use the latest research equipment.

A unique warehouse-size structure where the air is filtered to remove microscopic particles and where people entering labs don protective garb to minimize what officials called “bioburden” will hold up to 20 mobile “clean rooms” the size of trailer homes costing up from $750,000 apiece. Six of the labs, which can float on a cushion of air like a puck on an air hockey table, already are in operation.

If a pandemic or bioterror attack occurs, the place is designed to suspend its day-to-day work, be reconfigured easily and focus entirely on finding and making a vaccine to combat the threat. The goal is to provide a vaccine in 12 weeks, about half the time it took researchers in 2009 to address the H1N1 – or swine flu – pandemic. As many as 50 million doses would then be manufactured within four months.

The project is a response to ongoing concern about bioterror threats.  In 2010, the Commission on the Prevention of Weapons of Mass Destruction Proliferation gave the government a failing grade for its efforts to prepare for and respond to a biological attack.  The new centers should be a strong step in the right direction.

Hollywood Technology for Police Training? Real-life Trainees Use Virtual Simulations

leave a comment »

According to a 29 May 2012 article in Homeland Security Newswire, some of the technology which makes the movie worlds of “Lord of the Rings” and “The Avengers” so realistic is now available to help law enforcement officers train for hazardous situations.  Raytheon’s motion-capture method allows trainees to interact with live people or with avatars, all in a 360-degree virtual environment.

Homeland Security Newswire explains how the technology works:

The system works with reflective markers placed on users’ bodies that track their movements along a basketball court-sized “field.” Wearing lightweight goggles, participants are completely immersed in a highly realistic virtual scenario, such as a hostage rescue or a variety of other incidents.

The goal is to re-create on-the-job, realistic challenges so that officers can be better prepared and equipped to deal with them.

It’s easy to imagine how this kind of training environment could let homeland security officers practice essential skills for high-stakes incidents.  Terrorist hostage-taking, bombs and booby traps, and WMD incidents are hard to prepare for, because realistic training situations are traditionally difficult to create or even dangerous.   With Raytheon’s VIRTSIM training system, officers may be able to try out their skills in a realistic, yet safe, virtual environment.

What do you think of game-type simulations as a way to practice HS skills?  What are some potential downsides of these training methods?

Getting the most from your online education.

leave a comment »

Make your education a priority.

Treat your online education like traditional schooling.  Just because the education venue is online, it doesn’t mean you can study “when you have nothing else to do.”  College (online or brick and mortar) is a commitment and you must set aside certain hours to attend school – online lectures, study, reading, doing homework and taking exams.  Making your education part of a weekly routine and sticking to that routine is important to the learning process.  Self-discipline is very important.  A time-management strategy is also important.  Students who have established their own schedules for class find that it helps them ensure time for daily class participation.

Treat it Like Traditional Schooling

Falling behind is easy in online classes… and catching up is tough!  The benefit of an online education is the flexibility and your ability to set a schedule that benefits you and your busy lifestyle.  It is easy to work around your other activities with online classes.  However, you do have deadlines, so you must set aside a block of time EACH day to complete your coursework.  Once students get into the habit of falling behind in their work, they tend to have trouble catching up and keeping current with the coursework.

Get involved?

Don’t be a virtual wallflower!

It is important to participate in your class and interact with your instructor and classmates in order to take full advantage of all your education has to offer. And when you participate, share your thoughts and opinions. Because of the nature of distance learning, many of the pressures associated with socializing are minimized. Your classmates and teacher will get to know you through your thoughts and contributions to the class.

Like so many things in life, online college delivers pretty much what you put into it.  The more you participate in online discussions, question your fellow students and instructor, and show what you know from class readings, the more you will gain from this experience.

Like in a regular classroom setting, you must make an effort to “stand out” in order to be sure your teacher and fellow classmates are aware of you. Interacting with your instructor and classmates is important and should be done as often, and as directly, as possible.  Make sure your posts are relevant and complete, and that you’ve used spell checking, but don’t obsess about your writing skills.  Just as it’s important to speak up in an onsite class, even if you’re not an amazing public speaker, you need to be visible in your online classroom.

Just like in a regular classroom, some students will be more involved than others.  While you are not seated amongst your classmates, the online format and the many options for communication can still make for a very dynamic and engaging experience. For example, most students are required to respond to the posts or comments of other students. Don’t just do the mandatory three or four replies…do as many as you want and really interact with as many classmates as possible.

Communicate with as many classmates as you can, and try to overlook any early misunderstandings between you and your peers.   Disagreements are a vital part of education; they challenge us to think about our own conclusions.  If you find some classmates are consistently obnoxious—or worse, uncommunicative—focus your energies on others who are active in class.  You’ll learn more by exchanging ideas with energetic people, even if you don’t always agree.

Just like attending traditional classes, logging into your course every day for updated messages, emails and other information will allow you be more successful in class.  If your instructor posts announcements and provides guidance, take the time to read it carefully.  You would listen to your instructor’s guidance in an onsite classroom, so don’t cheat yourself out of helpful information by skipping online hints.

Learn to ask questions. Don’t worry about how stupid or silly the questions might be, since you might want to keep in mind that there may be others around you that aren’t familiar with the concepts either.

Online classes can be more fun if you engage in conversations with your peers.  Taking responsibility for your own learning will pay off later.

Join Study Groups.

Yes, even online universities have study groups.  If you don’t see one for your subject area, create one!  There are lots of online tools for collaboration.  Working with a study group is a great way to master new material and get fresh perspectives on the subjects at hand.  Some people are skittish about online colleges because they fear the online experience may be impersonal and isolating. In fact, Internet-based technologies offer opportunities to establish all manners of relationships with students and instructors, friendships that can endure well beyond graduation. Take advantage of them.

Seek Help When You Need It.

Many online colleges have support systems in place to help students succeed at their studies. This can include everything from help with online financing to psychological counseling and career services support for graduates.  There’s also academic help on writing and study skills, two key areas for a new college student’s success.  If you need help, never be afraid to ask for it. It’s part of what you’re paying for.

Don’t Lose Touch.

Going to school is a great opportunity to network with instructors and fellow students.  Keep these networks active even after graduation. You never know when someone will be in a position to help you get ahead — or you’ll be able to help someone else.  Most jobs are found through personal networks, and it’s not too early to start building yours.

Technology marches on

with one comment

Technology doesn’t stand still in the Homeland Security field!  Several recent developments—from the fields of information technology, biometric engineering, and social psychology—are worth a closer look.  These are all available on the Homeland Security Newswire, which offers current reporting on technological developments in the security profession.

Frankenmalware

Many of us have probably felt our computers know more than we do at times, but we can still change and adapt, while they get obsolete, right?  Right… but there are now indications that snippets of programmed code have recombined in ways their creators never planned.  Unfortunately, these bits of code are malwareviruses and worms.  Viruses have been seen to accidentally make use of worms, propagating themselves more effectively in a “malware sandwich” or “Frankenmalware.”  According to a post at the Malware City blog, this is how it can happen:

Now, another “practice” has silently emerged: the file infector that accidentally parasites another e-threat. A virus infects executable files; and a worm is an executable file. If the virus reaches a PC already compromised by a worm, the virus will infect the exe files on that PC – including the worm. When the worm spreads, it will carry the virus with it. Although this happens unintentionally, the combined features from both pieces of malware will inflict a lot more damage than the creators of either piece of malware intended.

It may also be that in some cases, cleaning by antivirus programs may help altered malware escape detection.  Read more at http://www.malwarecity.com/blog/virus-infects-worm-by-mistake-1246.html/

Handy fingerprints?

Biometric systems are increasingly common.  However, the need for stationary equipment to read and process prints has limited its utility in some fields.  Now, researchers at Neurotechnology have developed an application which allows smartphones and other mobile devices to run scans almost anywhere.  The mobile products contain the same algorithms as the company’s PC-based versions of their products, which meet AFIS-level recognition standards.  Homeland Security Newswire explains that these devices can handle fingerprint or facial recognition quickly, with iris and voice capabilities on the way:

The company says that VeriFinger Embedded and VeriLook Embedded can process fingerprint or face images in less than one second using a device with a 1GHz or better processor. The first available release of the new MegaMatcher Embedded product includes VeriFinger and VeriLook fingerprint and face biometric algorithms, and versions incorporating iris and voice biometrics are planned in the coming months.

Happy, sad, silly, mad

Remember learning about smiles and frowns in preschool?  Actually, sorting out human facial expressions isn’t so simple, but researchers at King’s College London have isolated the characteristics of a face displaying anxiety.  Their research, published recently in in the Journal of Personality and Social Psychology, shows that the emotion we call anxiety is expressed by an environmental scanning look that appears to aid risk assessment:

The characteristics of the facial expression for anxiety comprised darting eyes and head swivels that echoed the risk assessment behavior of anxious rodents. These results suggest that the anxious facial expression in humans serves to increase information gathering and knowledge of the potentially threatening environment through expanding the individual’s visual and auditory fields. Therefore the anxious facial expression appears to have both functional and social components — its characteristics help assess our surrounding environment, and communicate to others our emotional state.

The lead author of the study, Dr. Adam Perkins, noted that the findings could help security personnel identify individuals engaged in wrongdoing by means of their anxious, risk assessing facial expression, as well as helping mental health professionals assess their patients.

Drones in the Sky or Boots on the Ground?

with one comment

Unmanned aircraft– Predator drones— have moved from the battlefield to the border.  U.S. Customs and Border Protection (CBP) will soon have six of the aircraft active in the effort to detect smugglers of humans and illegal drugs.

According to a 14 November 2011 Associated Press article by Christopher Sherman, the Predator program is credited with helping to apprehend more than 7,500 people and intercepting 46,600 pounds of illegal drugs since the first aircraft were deployed in 2005.  Here’s the article’s description of the Predator at work:

Two Border Patrol agents walked by a patch of brush on a remote ranch and saw nothing. But 19,000 feet overhead in the night sky, a Predator unmanned aircraft kept its heat-sensing eye on the spot…  

In an operations center about 80 miles away, all eyes were on a suspicious dark cluster on a video screen. Moments later, the drone operators triggered the craft’s infrared beam and pointed the agents directly to the undergrowth where two silent figures were hiding.

Officers involved with the program noted that the drones are affected by weather conditions, as are humans and other equipment, and that there are political sensitivities involved when their missions take them across the international border with Mexico.

The biggest issue, however, is price. Each Predator system, which includes the aircraft and its sensors and control equipment, costs $18.5 million.  According to the AP article, some Homeland Security specialists question whether the drones’ impact justifies the price tag:

“The big knock on the UAS (unmanned aircraft systems) program … is that it’s so expensive,” said T.J. Bonner, former president of the National Border Patrol Council, the agents’ union. He said the money would be better spent on more boots on the ground and manned aircraft.

As future Homeland Security professionals, what do you think?

Homeland Security and the Rise of Social Media

leave a comment »

Social media, such as Facebook and Twitter, are a growing factor in everything from marketing to politics, and Homeland Security is no exception. We see the rise of social media in several areas of professional concern:

  • Counterterrorism, in which we’re aware that terrorists increasingly use these technologies to reach out to potential recruits and communicate with operatives;
  • Emergency response, because social media are a fast and effective way to communicate information in a disaster situation;
  • Epidemic disease, in which people worldwide can report instances of disease outbreaks instantly, circumventing any effort their governments may make to contain the information.

Like any essential change in the way people communicate and get things done, social media have their drawbacks. First, it’s worth noting that only a small fraction of the world’s population uses them. Because this fraction tends to be young, well-informed, and activist, social media helped propel popular reactions in places like Iran and Egypt. Nonetheless, it will be a long time before social media catch up with Internet applications like e-mail and news sites, let alone with television, radio, and telephone communications.

Let’s look at some of the challenges Homeland Security professionals will need to consider as social media become more pervasive.

In the area of public security, there was an incident in Mexico in August 2011 in which two individuals, labeled the “Twitter Terrorists” in press reports, posted false information on Twitter and Facebook claiming that children had been abducted from a school in Veracruz by drug cartels. The posts allegedly led to traffic accidents as parents hurried to the school in a panic, and the two perpetrators were charged with terrorism.

The charges were later dropped, but the incident highlighted two important points. One was the degree to which people in Veracruz, an area hard-hit by narcoterror gangs, used social media for instant security-related information. Checking Twitter before leaving home, for example, allows residents to learn about gunfights or other hazards.

Another is the ease with which anyone could cause terror and even casualties by spreading false reports via Facebook or Twitter. As in this case, people might be injured in traffic or trampled at a public gathering based on such reports.

Epidemic disease, whether of natural origin or the result of WMD use, remains a fearsome threat to Homeland Security. In a November 3 article, Homeland Security Newswire explains that social media can sometimes lead to inaccurate information:

Social media sites like Facebook and Twitter have proven useful in quickly disseminating information, and raising awareness during disasters or disease outbreaks, but these tools can also be a double-edged sword. 

Global health officials warn that social media sites often spread rumors or false information that are difficult to correct.

Margaret Chan, the director-general of the World Health Organization (WHO), said, “I can assure you that with the rise of social media, the background noises for rumors have become much louder and making it so much harder to detect the really important segments.”

Keji Fukuda, the WHO’s assistant director-general, echoed Chan’s thoughts pointing to rumors circulating around the Internet on how to build immunity against the H1N1 swine flu during the 2009-2010 outbreak.

One of the rumors which started was that if you increase your salt intake it can help,” Fukuda said.

According to Fukuda, the agency was forced to correct the rumor, using social media, because taking in too much salt can be dangerous.

Emergency response is another area where the dissemination of inaccurate information could be a problem. However, the benefit of quickly spreading helpful information during a disaster makes it an option to expand, not squelch. Agencies like FEMA are already using social media to inform residents of what’s happening and what to do, and individuals use them on a personal level.

According to an article at Mashable.com, there’s room to make this role more formal:

However, according to new research from the American Red Cross, the Congressional Management Foundation and other organizations, social media could stand to play a larger and more formal role in emergency response. In fact, almost half the respondents in a recent survey said they would use social media in the event of a disaster to let relatives and friends know they were safe.

Students of Homeland Security are sure to see social media technologies grow in prevalence and power. You’ll likely confront new forms of communication yet to be imagined, so it’s worth considering how to make best use of these technologies in the public interest.

Resources for New Entrants to the Homeland Security Profession

leave a comment »

Looking to put your Homeland Security education to work?  Read on for some resources to explore as you look for positions which suit your experience and interests.

Every candidate is different. Among the factors to consider are your willingness to relocate, your past experience (especially in security-related work such as firefighting or military specialties), your age (some entry-level Federal positions have an upper age limit, usually 37-40), and your interests. A few positions will also require eligibility for security clearances. Many positions you’ll see are suited for people who are already working in the HS field, so keep on looking for those which suit your own level of experience. Some will require additional training, such as an EMT certification, along with your HS degree.

It can seem discouraging to look for your first position in a tough economy, but take heart– Homeland Security is one of the fields less affected by the downturn. Realize that you’ll likely need to go through a lot of applications before you land your position. That’s entirely normal, and it doesn’t reflect on you.

If you’re not already looking at USAJOBS, that should be a regular part of your search if you’re interested in positions at the Federal level, like FEMA work. USAJOBS is the site for Federal employment, and it lists civilian and military positions at all levels.

Monster.com is the big name in employment searches, and it features millions of mostly private-sector positions in all fields. It’s worth searching, and you can set it to send you reports on security jobs in the areas you want.

Another good one is Indeed.com.  It also carries jobs in all fields, including security.  These include positions in emergency management.

State and local positions may appear in job databases, or on their own agency sites. There’s a lot of variety here, so you’ll need to do some investigating to find the listings you need. If you’re interested in emergency management or law enforcement, look at your own state’s websites, and then at some in your city (or other cities where you could relocate). Here is one example:

Police officer in Bismarck, North Dakota: http://tbe.taleo.net/NA5/ats/careers/requisition.jsp?org=BISMARCK&cws=1&rid=249

There’s a site dedicated to emergency services jobs, too. Check out listings at http://emergencyjobs.org/.

Open Fire Academy offers a great list of positions in firefighting and emergency response. Some of these positions require firefighting or EMT certificates that you may have earned as a volunteer, or which you might work on completing to complement your HS degree.

Remember that few people find their dream job right out of school. Depending on your goal, you may need some years of experience, and perhaps additional training. For example, if your ambition is to be an FBI officer, you would do well to gain some entry-level law enforcement experience with a local police department– something your HS degree makes you well qualified to do. Then, you can work on your bachelor’s degree while racking up the experience you’d need to reach your goal. All the while, you’re earning a salary and benefits. If you’re aiming at a position with TSA or CBP, you won’t need any additional training or education, but you’ll need to prepare for entrance testing.

Of course, most people find that their priorities and interests develop as they progress in their careers, so your goals may change, too.

Chat-downs: Behavioral Science at Work

with 2 comments

The Transportation Safety Agency (TSA) has a tough job, and it continues to look for ways to stop terrorists while minimizing inconvenience to legitimate travelers. Sometimes, the emphasis is on technology, but a successful pilot program involving focused questioning and observation by a trained officer shows that behavior analysis techniques work.

An article in Business Week magazine explains that the program will soon be expanded to a second site:

Detroit Metropolitan Wayne County Airport joins Boston’s Logan International as a test site for the program, in which TSA employees briefly talk to passengers to assess whether they might be involved in terrorist activities. The technique has been called “chat-downs” by Representative Bennie Thompson of Mississippi, ranking Democrat on the House homeland security committee, who has questioned whether it works. “

While there have been a number of naysayers about this technique, my main question is, “What took them so long to implement this method!” Behavior detection is the way to go for TSA and I would like to see this spread to include many more airports. The chat only takes a minute or two, and it can be very revealing of individuals’ motivations, fears and worries. People involuntarily show physical and physiological reactions to a fear of being discovered, and when briefly interviewed by authority figures, anxiety is intensified– allowing officers to detect these reactions. While electronic detection equipment has its place, focused observation is more likely to lead to an individual’s motivations and intentions.

According to the TSA website,

“The Behavior Detection Officer (BDO) program utilizes non-intrusive behavior observation and analysis techniques to identify potentially high-risk passengers. BDOs are designed to detect individuals exhibiting behaviors that indicate they may be a threat to aviation and/or transportation security. The program is a derivative of other successful behavioral analysis programs that have been employed by law enforcement and security personnel both in the U.S. and around the world.”

Many of TSA’s techniques have been pioneered by the Israelis, who have been struggling with the terror threat for much longer than the US has.

Behavior detection is a risk-based approach which allows TSA to focus its limited resources on making a determination whether someone is really a risk or not. This saves time for travelers who are non-threats and who can pass through these checks with no problems. It is not profiling, since determinations are made based on a number of factors including body language and responses to questions, and not on the religious or ethnic make-up of travelers. This is smart, given the fact that terrorists come from different religious and ethnic backgrounds.

This isn’t a new method; in fact, it has been practiced by the airlines for many, many years. For international flights, it has been common for airline personnel to ask questions of travelers such as whether they were given anything to pack, or whether they packed their own bags. This allowed airline staff to gauge reactions and focus limited resources on possible threats rather than mindlessly subjecting everyone to the same level of scrutiny.

Behavior detection is a risk based approach which is much needed in TSA’s methodology and is, at last, a logical way to proceed.  Those who don’t support this method may be basing their opposition on a basic misunderstanding of what it entails, since it relies on established behavioral analysis techniques and avoids the privacy and profiling pitfalls of alternative measures.

A “Pre-crime” System?

with one comment

 

Is it possible to detect terrorists or criminals before they strike? That’s the premise of science-fiction films like Minority Report, but the Department of Homeland Security (DHS) is already experimenting with a “pre-crime” system it calls Future Attribute Screening Technology, or FAST. In an October 7, 2011, article, CNET News writer Declan McCullagh explores what FAST is intended to achieve.

Instead of relying on psychics to predict who will commit a dangerous act, FAST is designed to collect data surreptitiously on a subject’s heart rate, breathing, voice patterns, eye movements, ethnicity, occupation and gender. Algorithms will then determine which individuals may have malicious intent.

So far, FAST is still in the testing phase. In addition to testing on DHS employees who volunteered for the program, a field test was conducted in one northeastern US venue. How would it be used? DHS has suggested that FAST may be deployed at airports, but it might also be used at border crossings or public events where large crowds are present.

How about the science behind FAST? There’s no way to conclusively detect someone’s criminal or terrorist inclinations; that idea went out with phrenology in the 19th century. However, biological signs can betray a person’s anxiety, and someone who is about to commit a terrorist attack is likely to be under stress.

One problem is that while symptoms like an elevated heart rate or changes in voice patterns may indicate anxiety, they don’t offer insight into the cause of the anxiety. Someone displaying these symptoms may simply be nervous about missing a flight, or may be stressed at a sporting stadium because of misplaced car keys or even an adverse referee’s call.

There’s a parallel with “lie detectors.” Polygraph equipment can’t look into someone’s mind and determine that he is lying. All it can do is reveal biological symptoms which are associated with the anxiety or stress. Since stress accompanies deception for most psychologically normal people, it can indicate areas for questioning for investigators.

Because FAST won’t be able to “detect terrorists” in a simplistic and certain manner, we as Homeland Security professionals will need to consider how technologies like this should be used. There are clear privacy implications: how would collecting data from crowds of people square with the Fourth Amendment prohibition against unreasonable searches and seizures?  If a system like FAST does point out an individual with a suspicious profile, how should law enforcement or transportation security officers proceed?  Would it be sufficient grounds for probable cause, leading to further action?
