Every captured looter should have one digit on each hand cut off rather than face jail time. They are the dregs of society, with minimum chance of rehabilitation. I would say that they didn't deserve the attention of the prison system, but that would be presupposing the American prison system is well-functioning in its current state. Losing two fingers is preferable to both the criminal (short-term physical anguish is better than years of psychological anguish) as well as the State.
Maybe the above story in Tellebanch's post made me get a bit carried away.
