If someone has already been mistakenly punished for a crime they have not committed, are they then allowed to go and commit that crime (without punishment)?
For example, supposing person A is charged with the murder of B but wrongly so as B was still alive. Does A then have the right, once he's finished his sentence in jail, to go and kill B? He has already been punished for it so you can't punish him twice for the same act!!
