Speaking of the TSA, check out what Steve Moore, former FBI agent, has to say about them:
TSA has never, (and I invite them to prove me wrong), foiled a terrorist plot or stopped an attack on an airliner. Ever. They crow about weapons found and insinuate that this means they stopped terrorism. They claim that they can’t comment due to “national security” implications. In fact, if they had foiled a plot, criminal charges would have to be filed. Ever hear of terrorism charges being filed because of something found during a TSA screening? No, because it’s never happened. Trust me, if TSA had ever foiled a terrorist plot, they would buy full-page ads in every newspaper in the United States to prove their importance and increase their budget.
