So, an FBI agent boarding a plane apparently tried to do so with a loaded pistol magazine, resulting in his arrest. The temptation is there to mock the dude, but I know how one can forget these things; there's a reason I never take the bag I use for a carry-on anywhere near the range if I can help it.
Unfortunately for the agent, he was not trying to board a plane at Sky Harbor in Phoenix, where he would have gotten a stern talking to and maybe lost the magazine if he didn't want to miss his flight. No, he was catching a hop from Karachi to Islamabad and, apparently unlike many US states, there's no mens rea requirement in Pakistan for what he did, so they arrested him.
The funny part is what they charged him with:
Charging a man with terrorism in this place is like handing out speeding tickets at the Indy 500."
Coincidentally, I just got back from the range, where one of the guys was relating what happened when he had forgotten some live rounds in a coat pocket on a recent trip. It didn't involve Pakistani prisons, I'll tell you that.
