No of wouldn't alone provide justification for shooting.
But it certainly adds credence to the officers claims the guy fought him for his gun.
IF that is the guy and he just robbed a store violently do you think he'd just say "ok coppa ya got me"?
You're right. Surely he'd lesson his criminal liability by adding the crime of killing a cop to his rap sheet.
So, is there any actual evidence that this man posed a threat of lethal force at the time of the shooting, or are y'all going to continue to rely on hand-waving and misdirection?
No. You know what would add credence to the officer's claim? A video recording of the entire stop. Frankly, I'm inclined to assume guilt on the part of any officer who fails to acquire or produce such, and I'm inclined to suspect I'm wholly correct in doing so.
