[2.2 Straight six]

if it was all bullshit then the Scotland Yard wouldn't have caught 26 would-be bombers in one night and wouldn't have prevented a potential attack.

yea, sometimes stuff slips through the net. but the fact that attacks really aren't that often shows that security works. just remember, they won't always tell you when they've caught someone, so you're not alarmed.

and yes, there are ways of getting things past x-ray machines. there are readily available substances that x-ray machines just can't see through at all. but i won't share what they are.
