Automatic Scanning for Highly Stressed Individuals

What if the potential "bomber" is a calm person

 

You think a bomber is going to have a red face, more likely he is going to be methodical and slow and calm and getting small details right the first time

 

I wonder if opium is a fringe benefit.

 

Those that send out bombers will find people that can stay calm. Probably will also find a few pharmaceuticals that can mask the signs.

 

That shouldn't be a problem! Then a new technology will be invented that will also tag the calm people as bombers!

 

On the surface they may look calm, but inside there must be some sort of excitement before doing such an act. At least the heartbeats, blood pressure, sweat, micro movements etc would be different than people under "flat" condition. The hard part is, how do they differentiate between "being excited to bomb a train station at busy hour" and "being excited at the first-day work of the job one has been wanting for so long"? And besides, spotting the culprit on the spot (lol words juggling) is way too late. Instead of unnecessarily keep bothering with small minions (which will never be running out of numbers anyway), it's better just to dispose of the key people in terrorist organisations, they usually will collapse almost automatically after that due to lack of leadership.

 

Being a 'person of interest' and getting whisked off by the swat team; interrogated: on record as having been singled out as a possible suicide bomber; found to be merely stressed out; and now permanently under surveillance. Now this guy is really stressed out!
