I think it's a safe assumption, because if the TSA actually found a terrorist through its screening process they would parade this achievement in front of every news organization it could. On the other hand, there have been numerous documented cases where people have deliberately snuck banned items through the TSA security checks. Of course, you had to qualify statement that the TSA "has performed fantastically" with the number of _successful_ attacks. There have been terrorists that have attempted attacks, such as the underwear bomber and the shoe bomber, but those were all stopped by the passengers. To me, this should have warranted a congratulations to our fellow citizens for being vigilant - and maybe even a relaxation of some of the rules. As you know, the opposite occurred, and now we have to take our shoes off and can only take small amounts of liquid. Who's being naive?
