At the moment I kinda' like Israel's approach to airline security, and it's no secret that I'm often critical of Israel, or more accurately, it's government. They profile passengers, review flight manifests, both inbound and outbound, and have a sky marshal on all El Al airplanes armed and trained to shoot any ne'er-do-wells, which is so common sensical that must be why no one else does it. And you don't have to remove your shoes, your belt, and you can carry on liquids because if you were a threat they wouldn't let you on the plane in the first place. And if you still turn out to be a threat, the sky marshal takes you out.
