What if every thief received this treatment? I think the need for police to investigate theft would diminish. The space between the crime and the lack of punishment makes it more likely that the action will be repeated. A swift retribution lowers the chance of repetition. Just take a moment and picture what is in the mind of this perp the next time he contemplates stealing a phone… if he is shopping for a stainless steel cup, we know some limited learning has occurred. If he gives up on that activity as the risk of pain is too great, then society has benefited.
