I think this gets to the meat of my disagreement with Mr. Sela, and that's about behavioural profiling.
I'm going to be as provocative as possible to make the distinction between the two arguments extremely clear.
I do not believe one has behavioural profiling that is independent of culture. I think we need to be wary of engaging a system of behavioural profiling that makes the same assumptions about how we react to stress and authority. An obvious example is eye contact with individuals who are in a higher position of authority. In western culture, we take that as a sign of respect and a sign of confidence, whereas in other cultures it's read in an entirely different way.
I know that Mr. Sela will be able to speak to this in a different way, but I'm concerned that the behavioural profiling brings with it certain racial, ethnic, and linguistic stereotypes that we would not wish to follow.
