I wonder how much it would cost to start keeping an armed guard on every flight. That's what the Israelis used to do and it seemed like it worked fine for them (they might still do it, but it's been awhile since I've flown through Ben Gurion airport).

Actually, the Israeli security model seemed like it made much more sense with a lot less theater.

When you check-in, your bags are unpacked on a table and the contents are inspected with you standing there.

You pack your bag back up, they tape it with security tape and send it down the conveyor. The ticketing agent then does a short security interview with you regarding where you're going, did you pack your own bag, etc.

You get your tickets and go through the security screen - metal detectors, x-ray, perhaps additional screening if they suspect something. No genital grabbing, no pornoscans (although, my brother did get semi-strip searched once, due to telling a white lie and getting caught at security).

There's an additional interview with customs / immigration before you get to the gate, but that's mostly for passport control issues.
