What did the idiot in the video expect everyone to do? Perform a "citizens arrest" on the guy stealing the bike? What if the guy wasn't even stealing the bike and just lost his lock key? Is that person supposed to do some kind of detective work, for you? I don't think so...

You leave your bike, you take your chance. Just like eveyone else. It's a calculated risk. Don't depend on someone else to save your sorry a$$.

It doesn't take a village.
