City of Tahlequah, OK v. Bond
Officers responding to domestic violence call entitled to qualified immunity on ground they did not violate any clearly established law when they shot and killed suspect who raised hammer behind his head and took a stance as if he was about to throw hammer or charge at officers; Court does not reach issue of whether officers who recklessly create a situation that requires deadly force would violate Fourth Amendment, distinguishing cases that stand for that proposition from this case on the facts.
