In this youtube video a guy named Adam from Adam vs. The Man does some excellent filmaking to inquire of the TSA how many terrorists the TSA has caught. Their answers are amusing and disturbing. This website considers them a violation of our natural right to travel, and will be a common theme on this blog. It is 100% legal to film in a public place, including airport security checkpoints. However, over and over again the TSA will tell you that you cannot film, another violation of your natural rights.
The TSA is just security theater.
