Nobody forces you to fly in a plane against your will. Most people are aware of the risks, and make a calculated choice to fly or not. If you get arrested, convicted, and executed for a crime you didn't commit, you didn't get to decide whether to take that calculated risk or not.
I'm sure if you ever got arrested for a crime you didn't commit, and put on death row, the difference would become immediately apparent.
Would you agree that a death caused by the existence of the police force meets the same criteria?
(Again, i'm not really thinking this through, so i might be missing something).
