It seems more bad guys die when you cut the police force.
That could permanently clean up a lot of bad, if instituted everywhere.
This must be what Black Lives Matter sees, too.
It means that a lot of incidents get just one officer responding, without backup. With multiple officers, you have a higher probability of being able to subdue a guy without needing to use deadly force.
If I was a lone officer facing a crackhead with a crowbar, my attitude would be "Screw this, my priority is getting home tonight unharmed. He either drops the crowbar when ordered, or I empty my magazine into him".
