A Pakistani man who got too lippy while he was being held in a Pakistan detention facility had his mouth sewed shut by the police who were holding him. Five of them have been fired for it. I don't think that firing was a good enough punishment but that's not the point I wish to make in this post. My point is this: "don't ever sew anyone's mouth shut when there is duct tape to be had." They should have used duct tape. Duct tape would have both staunched the flow of abuse from the prisoner, and allowed the police to blow off a little steam, all the while not causing grievous harm to anyone. But make darn sure the recipient deserves it.
