Dont get me wrong. In my world, you kill or hurt someone while driving drunk, you'd never get out of jail.
Not in MY world. In JUCOT (Justices Utopian Community Of Tomorrow) the above person would be meeting Judge Dredd for a summary execution. We would then cut his head off and run over it with a steam roller. (This would of course be done to make sure science could never reattach it.)
