I think the one big problem in the Israeli process is the fact that you will require a fairly high level of training in personal skills to be able to achieve this level of security; given the calibre of many of those working for the TSA and other security organisations (the phrase "marine corps wannabes" comes to mind), hired at fairly low wages - and not even (initially) allowed to become unionised, would they be able to carry out this level of security? Experience has shown that many security personnel take a confrontational approach, which of course antagonises even the most relaxed of passengers, so the opportunity to observe behaviour is effectively ruined.
Not everyone is going to be capable of carrying out this kind of "behavioural recognition" and it's unlikely to be people on minimum wages, so will the TSA and others be willing to consider this expenditure?
And reading through the article provided by Graybeard, it occurs to me that too much emphasis is being placed on profiling; if everyone is asked the same questions and treated the same way (subject of course to their responses), then profiling should not be as big an issue as is being suggested?
