Yeah, glancing at an ID really keeps a terrorist from setting off his bomb.

"...he had a suspicious pair of shoes that tested positive five times for the explosive substance TATP on the interior of his shoes between the heel and sole. ...Strangely, after holding him overnight, airport security in New York released him. The FBI was notified after he was released."
Yeap, glancing at an ID makes us so much safer.
Oh,m i get it. You;re in the 'do nothing at all' camp.
Here: you have 1000 people on mass transit and a threat. Scenario 1 - all ID's are checked. Scenario 2, because of people who think like you no ID's are checked, nothing is done. Under which scenario (and please be honest) is there more likelihood of stopping the threat???
