Sounds like a real southern smackdown. Seriously, it reads real bad but I've learned not to second guess the officer. I've never been involved in an officer involved shooting, but we've had 5 since I've been with this department. It's a crappy thing for the officer to go through. In the People's Socialist Republik of Kaliforniastan, they are huge deals due to the litigation.
We had a bad guy with an AK folder stuck in his waistband. He tried to pull it out to shoot my buddy. My buddy shot him a number of times dropping him. They guy was still trying to raise the AK to shoot, so my buddy reloaded lickety split and shot him some more. The family members of the dirtbag heard it second hand that my buddy stood over the guy and executed him. They were nowhere near the incident, but rather heard it from a "witness". Of course the liberal papers repeated what the grieving family told them. My buddy started drinking a lot and eventually quit law enforcement.
They'll get the whole story ironed out eventually. Meanwhile, every Bubba who heard it from his second cousin twice-removed will be quoted in the paper while the taxpayers pick up Mr. Crutches medical bills. And Mr. Crutches probably has 5 lawyers already lined up to file a suit for him.
It'll come down to the officer's state of mind, perception of the threat, and his training. If he felt that he was in danger of great bodily harm, then he was justified to use deadly force. It doesn't matter what any of us think. It comes down to him convincing a grand jury. And as long as he was within department policy, the department will have his back. Was the cop always trained to fire two rounds and then assess? Did he fall back on this muscle memory that was ingrained through his training, as infrequent as that may have been? Probably. And of course, Mr. Crutches will file a civil suit, and the county will settle because it's cheaper to go that route than to litigate it.
Most of the time it seems the criminals have more rights than the cops. These are crazy times we live in.
