Lots of suicide attacks have been, if not prevented, then limited solely because of the strange actions, thousand-yard stare, nervousness, etc. of suicide bombers. Pretty much any story you read where a security person (usually a doorman or some sort) and the bomber were the only one's killed, there you go.
Public places are much easier to do this kind of work in because most people have the situational awareness of a lemming. They don't pay attention.
Passing through security checks, though, that's a bit harder.
Trust me, if they could, you don't think some of the terror groups over there wouldn't love to hit El Al? To show they could do it? Or even the terminal or gate area.
If they would like to, why haven't they? If it's so easy?
