I live in Newark. I'd be about 100 times more likely to get killed walking to the bus to get to the airport than I would be in the plane, even if we had no security at all.
Anyone willing to tolerate this shit is a drooling fascist who also doesn't understand security if they think this bullshit will stop even one determined and competent terrorist.
We should do security like El-Al, modifying it of course for the practical differences between the threats we face, and for our own constitutional protections. People say that would be "expensive" but then, these are the same morons who think we should piss away fundamental rights millions of Americans have fought and died for for hundreds of years. And these morons want to talk of "expensive?" Please.
