I do not have the scales the judges have to determine if the punishment fits the crime. One thing is certain you do not treat another human being. As a matter of fact you do not treat any living creature. It is wrong. It is extremely easy to behave humanly to people we like, sypathize. Maybe I have high expectations, I do not know, but I demand and expect from the police to treat people who are thieves, murdereres etc. also humanly and use force only when there is no choice!
