All this ridiculous hyperbole about voluntary pat-downs being "this side of rape," about the government being Borg-like, and about the focus on it somehow being the "Tea Party's fault" (through some bizarre hyper-partisan logic I've not heard
anyone use until today) are just obscuring the real point: Are these security measures effective or not?
Because these security measures have been so widely publicized (inevitably so), does anyone really believe the next attempted terror attack is not going to take them into account? The terrorists are often ignorant and have somewhat comical plans, but they do have access to TV, newspapers/magazines, and the internet.
Would it even have been effective in stopping the underwear bomber, the case that inspired the long-desired (by the TSA/Homeland Security at least) extra measures to finally go into place?
Probably not. It's still reliant on a flawed human being in a cramped booth staring at ghost images of thousands of naked people on a small screen for hours on end day by day while fighting boredom, fatigue, job dissatisfaction, laughter, disgust, and titillation (don't ask me why, but apparently some people get off on it).
They have to decide what's important enough to focus and zoom in on, and smaller details aren't always apparent without focusing in. The
underwear bomb was just some PETN powder sewn into the front of the underwear and a fuse. It wouldn't look much different from a man wearing a jock strap or a cup underneath his underwear. Someone wearing Depends or a woman wearing a maxi pad wouldn't look any different from someone who could be carrying enough PETN to blow a hole in a plane either. Do you think every person wearing any of those things is getting a focused inspection under the scanners in enough detail for a fuse or blasting cap to become obvious? The pat-downs are voluntary if you choose not to go through the scanners. If you're the type of person who's willing to throw your life away so easily, you wouldn't hesitate to take your chances going through the scanners with the possibility of being caught.
Terrorists rarely try the same tactic against the same type of target any more - at least when going after nations with extensive intelligence agencies and security measures. The first WTC attack was a van that exploded in the subterranean parking garage, the next was hijacked planes crashing into the upper floors. Passengers will now jump anyone who tries to hijack a plane, so they've switched to bombs. When shoe bombs failed, they switched to underwear bombs. When underwear bombs failed, they sent explosives via printer cartridges in cargo planes. Reactive measures, especially against a powder explosive like PETN which can be hidden in virtually anything, are largely a waste of time. Banning liquids and now printer cartridges just means they'll pack it in something else. Giving "enhanced pat-downs" just means they'll carry the explosives in body cavities next, and that's a line in the sand I don't think even Homeland Security will cross where it comes to standard searches.
Also, baggage handlers and other airport employees don't go through the same searches passengers do, so it's not unlikely that a terrorist could pose as or get an actual job as an airport employee, giving them access to cargo, the planes, or large groups of passengers.
While I'll gladly take the Israeli's advice on airport security since they have more expertise then anyone, it's also good to bear in mind that the US handles over two million passengers a day, meaning we could fly the entire Israeli population in less than four days. The entire country of
Israel also has fewer international and domestic airports than just the
New York metropolitan area. Obviously the same measures the Israelis use aren't always practical given the number of people we have to process in the US and the number of TSA employees we'd need to train extensively, but a middle ground between the overzealous and often pointless pat-down measures we're using today and the behavioral profiling/interview-based measures of the Israelis needs to be reached.
