Here, thanks to Jeff, is a description of how the Israelis do airport security. They perform multiple checks, all based on looking at the person rather than his or her things. I've included it just so you can know, as you pull off your shoes and stuff them in a plastic bin at airport security, that "the goal at Ben-Gurion is to move fliers from the parking lot to the airport lounge in a maximum of 25 minutes."
And it gets worse. According to the article, the Israelis have a coordinated intelligence gathering operation that generates "a constantly evolving series of threat analyses and vulnerability studies," while neither Canada nor the United States does anything like it.
