The new standard: you only draw if there is an imminent threat of death or grave bodily harm. If you use "his hand was too close to his waist" as an excuse to draw on someone, or you draw before seeing them actually pose a threat, you go to prison for a very long time.
While we're at it, ban police unions, and don't require a conviction to have a bad cop removed from their job. Better safe than sorry.
