Baghdad Bob sez: ...now we're funneling people with bad intentions towards our expert-trained document checkers and behavior experts.

630 of 650 were not "bad" people, nor did they have "bad" intentions. Yet you wasted 630 X ten minutes X maybe three TSA + 1 LEO + the victim themselves, or 525 man-hours to not catch them. When if you had just patted them down, and found no weapons, the skies would have been IDENTICALLY SAFE?!?!?

Idiots. Pure self-rationalizing idiocy.

He even used my phrase about "no self respecting terrorist", but entirely missed the point when he said: Could a bad person produce an excellent fake ID and get past document checkers... sure.

EVERY bad person is going to have excellent fake ID. Assume it's true and don't waste time confirming the obvious! Your true opponents are clever and competent. Emulate them!
