We should be more precise.

> "... because he repeatedly set off the bomb detector."

No, the initial pat-down set off a chemical detector. He set it off once before being pulled into the private room. From that point on, it doesn't matter how many more times it was set off. It shouldn't increase the level of suspicion each time.

Would they have let him go if one time it suddenly stopped giving a positive signal? I doubt it.

> "These sorts of batteries were pioneered by the Israelis and are very effective."

But this is not how the Israelis run their security procedures, so the comparison isn't fair. http://en.wikipedia.org/wiki/Ben_Gurion_Airport#Security_pro...
