Look at the 11 Sept video of the asshat hijackers passing security. Calm, cool, and collected. Your several-hours-of-study voodoo would not work.
Scan all baggage (hand and hold) with proper working equipment. Make people pass through effective WTMD. Properly control airport access.
It can be done...
And if you bring up Tel Aviv airport I will send a scream through the computer as that has been debunked for so many different reasons I do not need to say it again.
Indeed. The notion that "international terrorists" are generally operating under duress and thus can be reliably detected that way is a canard -- if it weren't a canard, then most "international terrorists" wouldn't be criminally responsible for their actions to the extent they are, and massive cordon and search operations for militants in hotspots would be less ugly and more effective, timely operations than has been the case generally.
