A new video depicting a bike thief getting knocked around by an intended target and his friends confirms what we already knew: Stealing is bad, especially when you suck at it and your victims are likely to kick your ass. This particular genius attempted to lift a bike in broad daylight with a drill. Good thing he was wearing a helmet during the incident; it probably saved him from getting a concussion.

We've rounded up a few videos of would-be thieves getting a little comeuppance from marks who fought back. Think of this type of street justice as "When Victims Attack." Brutal? Maybe. Unquestionably satisfying to watch? Definitely.
