But you see how you'd have to prove the targeted bad guy was a good guy, and known that way to the government, right? Because otherwise you can't say "his right #0 was violated" in any serious sense, when he's bad enough to have lawfully forfeited his very life.

I can't imagine any court humouring this, but it could be fun to try.

Short of outright Death, can you think of any day-to-day example of a "my right #0 conflicts with your right #0"?
