So returning home from vacation on Monday the TSA busted me for having a tube of toothpaste in my carry on luggage. This particular tube has been with me on 7 flights in the last year and hasn't been a problem - or maybe it was a problem but just wasn't detected. Honestly I didn't even know toothpaste is a banned item since the TSA prohibited items page doesn't list toothpaste as near as I can tell and pastes aren't really liquids or gels - though it seems the TSA thinks otherwise. Interesting thing is all the screener did was toss it in the trash and send me on my way. Kind of a strange way to dispose of a potentially explosive compound - they do believe it might be explosive or they wouldn't confiscate it right? - and to treat a potential terrorist - I can get myself another explosive toothpaste and just try again the next day.
