That's not analogous at all.
Everyone drives, and so everyone is a possible source of a car crash. Police are not (in theory) just whoever wanders into the goddamn precinct. They're (in theory) trained professionals, educated in what they do, and therefore entrusted with both the force of law, and the deadly force they wear on their belts.
And no we probably can't make it ZERO, but we could surely get it under 1,300!?
