What if you are standing next to this guy in line waiting to be searched and get "blown up" when the cop wants to search him?
No offense but you are being terribly naive about "being blown up". The guys that wear bombs are neither intimidated nor deterred by random searches. If they are searched before they reach their destination, they just blow themselves up where they stand.
Additionally, the chances of the police searching the guy that is carrying the bomb is very low - insanely low. Why do you want to give up your freedoms for a futile approach?
On some days, my bag is searched three or four times. Library, office buildings, museums, etc. One more time won't make a difference.
