I don’t know how I feel about this video. On one hand, I’d want to do the same thing but with my U-lock. Had I caught the person who stole my bike three years ago, I might have lost my temper, too. On the other, it seems like assault since they don’t turn him in but just vent; it’s all after the crime (theft) has been stopped — maybe?
On both hands, is he just going to do it again? Did they accomplish nothing but venting (for which they might have a right I guess), or did they scare this guy out of trying to steal bikes (and maybe getting that drill in his forehead) in the future?
