I was in London once, and, on the Underground, a bloke tried to pick my pocket. He wasn't very good at it, and I felt him. I grabbed his hand, and broke a few of his fingers. I'm not proud of that, but he must never have forgotten that day, and it would have stopped him, at least for a while. I'm sorry about your i-pod, though.
nope! iPod jacked from my bag...
I should have known, damn muni...
