I think as police officers are constantly in the clear for putting down a citizen who threatens them with "something", I would think that defense would be an ace.
Most recent I can remember was in Perry, when a guy lead police a few miles in pursuit, pulled into walmart, hopped out of the truck pointing an ice scraper at the officer. Officer fired in what he perceived as self defense, was cleared days later. That officer did exactly as he should have. He responded to an immediate threat he perceived as imminent. Why would that defense not work for a normal citizen?
