Conclusion: United States transportation authority is only capable of reacting to threats rather than anticipating them. The measures they place to stop further crimes are worthless. We remain as "at-risk" as we ever were because terrorists are more creative than our law enforcement personnel entrusted to protect us. The terrorists appear not to be stupid enough to repeat the same crime twice. And the traveling American public appears to buy the B.S. they are sold, so far without question. How sad.
Solution: How about if we implement REAL airport security, like say they do in Israel. Israeli security profiles potential terrorists and implements additional security precautions ONLY when they are warranted. How about if we began using more bomb-sniffing-dogs that are known to be somewhere around 99.99% accurate as opposed to full body scans that are NOT. Just the combination of these two steps would increase security well beyond current levels, particularly if luggage (and airmail) had to pass the dog-nose-test before it entered the plane.
Instead: The government (which has LIED to the American public on multiple occasions and has intentionally put US citizens health at risk on multiple occasions for its own purposes) now tells us that the risk of radiation of full body scanning is "minimal". This is the same group that said that the machines were "incapable" of storing images until an investigation "proved" they were in fact storing images, which can be done by the flip of a switch. "Pat downs" are never going to catch an inventive criminal (a lesson drug mules already have a solution for), any more than any other intrusive measure has ever been successful to date.
Alternative: How about if until the government agrees to take real measures to protect us without giving every man, woman, and child flying in America a healthy push towards cancer - we, the traveling public, simply refuse to spend our hard earned dollars on air travel, or refuse either the pat-down or the cancer creator? Now that's an idea, even the tea-party should be able to agree with ...
