I flew from Atlanta a while back with a bunch of Trader Joe's 'Pound Plus' chocolate bars and a ten pound (!) Ghirardelli chocolate bar in my carry-on which got quite a reaction. The poor girl doing the screening seemed to think an explosion was imminent and was visibly distressed, quickly leaving her post and grabbing a supervisor. For those that don't know, big chocolate bars are organic material and look like explosives and I've seen this happen before - I was waiting to see the reaction.

The supervisor and the girl came back and I laughed and said 'clearly you have spotted my giant chocolate bar', and volunteered all the standard answers (yes I packed this myself, it's been with me the whole time, etc) and they calmed down. I was worried they were going to want to open the package which was a gift and I didn't want them all riled up.

We all learned something that day, they learned that big ten-pound chocolate bars are a real thing and I learned that terrorists can probably carry bombs on board as long as they are sealed in a Ghirardelli box. TSA didn't even bother with the swabs or sniffer dog.

Bottom line is that TSA agents have no skin in the game, if they miss dangerous items it's the passengers who suffer the loss, not the agents standing safely at their posts on the ground at the airport.
