The cop is an idiot. He unloaded all the rounds into scooter guy’s back.
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.
Shooting a suspect in the back is not always cut and dry as most people think and against the cops. That being said this is one time the officer involved used far too much force IF the guy in the scooter was immobile and unable to get up and walk. But if he was near a store employee or a citizen with the knife and within striking distance and threatening it was a righteous shoot. I don’t know the entire details so this is a call for the department and local prosecutors.
