Why not weed out the lazy cops? The cops that for what ever reason decide they are just not up for the run that day. Keep in mind it's not illegal own a gun in TN. Tennessee gun laws operate at the state level on a "Shall Issue" policy. The laws are considered gun friendly with no requirement for purchase approval or registration of firearms. So just having a gun does not mean he did anything wrong or deserved to be shot in the back.
So maybe police departments should recruit applicants that are in shape and physically fit. Capable of chasing down and catching a black male between the ages of 12 and 52 and doing their job which is to bring the innocent until proven guilty in to stand trial. Is that too much to ask for?
