Nobody said "shoot to wound". Police officers are trained to stop the threat and to use the minimal amount of force necessary to do that.

I doubt there is a LE agency in the state with a policy manual that has in it the phrase, "shoot to kill".

And I know the definition of Deadly Force: Force, the intended, natural and probable consequence of which is to produce death, and which in fact does produce death.

Also sounds like maybe you need to update your training regimen.
