I'm torn between public execution and life imprisonment. If it's execution, it should be public and at the risk of getting negged again for stating an opinion, the exectuion should fit the crime. It should be as brutal and painful as possible and it should last a long time.

If life imprisonment, the person should, as somebody said, be placed in population and every convict should know who the creature is and what they did and if they take action, the guards should be slow to respond.

Another thing...the trial and appeals, and appeals, ad nauseum, shouldn't drag on for years like they do. Retribution should be swift.
