In Britain for many years the main security measure at Heathrow was for security people to simply interview passengers on check in and ask them about their bags, where they were traveling, etc. -- the main purpose was to look for behavioral cues and not so much obtain answers to the questions. I believe this is one of the things TSA officers are supposed to receive training in.
I took the earlier post as referring to the events that happened after he was detained. I'm not arguing against the idea of "behavioural indicators", I meant to say that someone becoming upset at being detained, grilled, denied water, etc., isn't such an indicator.
As for TSA officers in particular - these are people who would be asking "Would you like a hot apple pie with that?" if it weren't for the existence of the TSA. Not exactly America's "best and brightest". I have serious questions about their qualification to make any kind of valid assessment based on subtle psychological / behavioural clues.
Says the guy who thinks someone traveling alone and carrying bug spray residue and being Hindu should set off the TSA's terrorism alarm. Perhaps you could move that bar a scorch higher?

You've led a sheltered life.
Not so much.
