Sigh.
We HAVE these things now. They're Behavior Detection Officers. The TSA employees them. Their job? To watch the lines and other places at airports seeing if anything looks out of hte ordinary or if anything does not fit and questions and probes people that they think fit a certain profile of issues.
For the love of pete people can be stupid sometimes.
PROFILING is not bad. In general, Profiling is a useful tool. The problem is and why there is this kind of push back is because Religious/Ethnic blanket, broad, profiling is ineffective and dumb. Spending your time interrogating or checking a guy because he happens to be named Akhmed while and acting like that's so much more important than the white woman whose acting nervous, has a one way ticket, nad paid for cash, is idiotic. Interrogating and checking Every Single "muslim", "arab", "Middle easterner", "terroristy looking" person is ineffective and will simply take up far, far to much resources and time.
Not to mention attempting to compare our security to Israel is a bit of a misnomer. How airports of the top two classifications do they need to do security for? There's three just in the DC metro area.
"Profiling" as a general thing isn't bad, and is used. Broadscale Racial Profiling when you're focusing on a particular race leads to less concern about other warning signs on those outside of that profile, which is dangerous, and is also incredibly inefficient.
