I think the policeman should be commended. He chose a flesh wound over a kill shot, in spite of the fact  that his life was clearly in danger. I wish more police would take note of this. Too many kill shots that could have been taken care of with less deadly methods. I understand that, with a gun pointed at you, your adrenaline  pumping, and you come up on a scene and a suspect that you know little to nothing about you tend to react instinctively for self preservation. But, I think more de-escalation training would be beneficial in learning how to cope with that instinct. I know I'll get flak for my comment, but so be it, won't change my mind one bit.
