They've had a security "Fast lane" program in place for years. It doesn't get advertised much, but TSA PRE and the Customs and Border Protection Trusted Traveler programs both allowed you to skip into at least a shorter line. http://blog.tsa.gov/2011/10/how-to-sign-up-to-participate-in-tsa.html
As someone with a degree in Security and Intel, I'm torn on the airport security aspect. On the one hand it provides jobs, but on the other hand it really is completely, 100% pointless, because you will never manage to stop that one crazy zealot from getting through if they are willing to die for it. We would be much better off financially and as a society if we just took a "well, **** happens" approach to alot of this and just went with the standard security precautions that the rest of the planet gets along just fine with. The liquid restriction for example. Could someone make a binary explosive bomb that would bring down an aircraft by combining liquids? Sure. But they could also swallow the liquids right before bording drug mule style and never be detected, and if they're going to blow themselves up anyways, they aren't worried about long term health risks. Could someone put a bomb in a shoe? Yes. Will it likely be large enough to even minorly inconveniance an aircraft? Probably not. yet every time I go to an airport they single out the guy with the big feet now.
We should concentrate on the simple, effective, and less obtrusive methods and scrap most of the rest of the system. While lowest bidder non background checked underpaid bribe susceptable safety workers are busy probing innocent grandmothers, Our nation's ship port facilities lack even basic sensors to detect a nuke. Guess which one I'm more worried about?
The aircraft already have door locks on the cockpits now. Hire more sky marshals. Put every passive sensor known to mankind on every wall of every terminal in the airports let everyone carry knives on aircraft again (try to hijack it with a boxcutter now, *****!) and cover the walls of the bulkheads in well publicized pig leather, and 90% of the problem goes away.
