He was ordered to produce ID. You don't follow the order, you die. You follow the order, you die. He didn't stand a chance. He was a black man, he had to go. The tail light probably wasn't even broken. The woman has said it wasn't.
See when was he ordered?
Before or after he told the cop he was armed
If the cop asked for the guy's license and as the guy was reaching behind his back he says I have a gun on me then the cop may well have been justified.
If the driver told the cop I have a gun on me and THEN the cop asked for the guy's license then the cop fucked up.
I have a hard time believing any cop would tell a person to produce ID after he was told the person had a gun on him.
He would have asked where the gun was and the driver should have kept his hands in plain sight
