Biggest crime you've ever committed?

[Egocide]

I went on a trip to England when i was 16 and as we were landing, a friend of mine says "hey, my brother collects these little life jackets they have under the seats. Lets grab a couple." So we put one in each of our bags, stupidly thinking that it wasnt really illegal. For some reason they have security checks on people getting off planes as well as people getting on them. This british lady puts my bag in the scanner and then the $hit hits the fan. James Bondish looking head official for airport security tells me and my friend (and the crowd of people surrounding us) that we may be charged with attempted manslaughter, because people "would have died without those lifejackets." My teachers are freaking out, we've been in England for 10 minutes and we're already in huge trouble. Eventually they let us go, as i was pretty sure they would. But thats the worst "crime" ive ever commited. (And this is post 9/11 so airport security was really pissed off that we wasted their time)
