> A threat of violence is not violence, a weapon is not violence, and an unstable person is not violence, and even violence doesn't justify killing unless that violence was life threatening. > If you're going to kill someone in self defense, you'd better have very convincing evidence or other means to show that they were in fact about to kill you. I don't understand this at all. A mentally unstable person shouting threats and approaching me with a deadly weapon is 150% enough evidence that my life is in danger. I can't see any other possible rationalization. It is a complete failure of the state to make someone scared of defending themselves against legitimate threats.
