with all the home land security bullshit. really. your crazy. Aside from the customs asshole thats dying to rip the americans shit apart, you have drug sniffing dogs, xray machines, and a whole lot more we dont even know about. If you do it,, make a bomb, slid it into the persons jacket who is standing in front of you and then start screaming on the top of your lungs "HE'S GOT A BOMB!!! HE'S GOT A BOMB!!!" I am sure you wont have any attention on you after that. lol
