There’s an amazing scene in the film M by Fritz Lang* where a serial killer of children is put on trial by the local criminal fraternity and the parents of those he has murdered. They decide, not surprisingly, that he must die for his crimes. And in the scene, the murderer, Beckert, played wonderfully by the wonderful Peter Lorre, tells them all that they cannot kill him, in fact they have no right to try him at all, because he is a man.
