Why is it Difficult or Impossible to Profile Terrorist Behavior? More often than not, the security agents in different locations such as air bases, ports and pubic places tend to look for certain behaviors in terrorists. According to Florence and Friedman (2010, p. 423), it is clear, that the most common form of profiling on terrorist behavior is what is termed as Screening Passengers by Observation Technique or SPOT. This strategy would employ looking at specific behaviors in such places. These behaviors could involve, appearing sweaty, carrying suspicious bundles and scurrying here and there looking over the shoulder. Later the security agents noticed that the terrorists had grown smarter.
