Why is it not zero? This strikes me as the exact sort of calculus they used way back when they stopped chasing fleeing suspects in vehicles: the danger to the public is too high to justify the use of force. If you can't hit your suspect without hitting other civilians, then don't fucking fire! And no I don't particularly care if the LEO's life might be in danger either, that's literally the job they signed up for: to put themselves in danger to enforce the law. It's ridiculous that cops just get complete power of life and death every time they feel a spot of stress, and have to be handled with kid gloves by the general public less they be murdered in the streets.
