Honestly, he would have been better off to dump all the rounds into the mobility scooter’s control box and then just sit out of knife range while laughing at the idiot stuck on the scooter. I’m all for shooting threats in the Tueller Radius, but... it’s a mobility scooter. You can low crawl faster than most of those things can go.
No way for the cop to know if it wasn’t just a lazy fat guy who didn’t really need the scooter or was using it as cover to steal. Granted, 9 shots in the back does seem rather severe.
Gad. Just walk over behind the guy and tip the scooter over. Taze or Mace him.
But shoot him? Good gosh.
