Great Article and oh so true...although I have to say this; it's better to be stupid and safe than clever and dead. Having made this unusual retort I would like to offer this; In the UK, after a terrorist attack a few years ago, a guy hat looked suspiciously Arab (not muslim...but Arab) was chased by police through the streets of London until he was caught in the subway and shot dead...only to be identified as a South American tourist! Why do I bring this up, because sometimes being over-sure is better than being under-sure...that means, if TSA's would be lax and just shoot suspects on sight, rather than just enjoy a slow aggressive queue of innocents...your article would be about stupid killings rather than stupid queues!
