In all reality they already do profile: http://www.tsa.gov/what_we_do/layers/bdo/index.shtm
Behavioral Detection Officers (BDO) are profiling folks all day long. It’s their job. It’s just not PC to use the word “profiling” just like the government has “quota’s” for minorities and women for employment but they don’t use that word anymore either.
It is good to know that there is some profiling going on. However, I wonder how many of these Behavioral Detection Officers are actually employed by the TSA. If I were to guess, based on appearances alone, I would assume that the numbers are quite low. Most of the TSA agents I have seen and encountered don’t appear to be highly educated and trained. They don’t look like they are “looking” for behaviors. They are just trying to get their job done, which is to move people from one part of an assembly line to the next point.
