While I'm not 100% sure I'd believe that the FBI looks at these, you couln't convince me that the TSA does NOT look at them.

Anything showing up "too many" ( >=0, maybe? ) times in this type of conversation will soon be on the banned list, even if they aren't on the official ones. Just like those dangerous iPods that got seized last year in Novermber and December- not on the list, but some inspectors felt they were dangerous.
