What do you mean?

5% of police in this country carry firearms. The car the victim was in was reported to be involved in a recent crime involving firearms. The car was seen by cameras which flagged it. The car was approached by firearm carrying officers, at least one officer fatally shot the occupant.

Did you read the comments? I still don't understand your Europe=US with gun violence take.

Edit: this has all been explained in the comment chain of your parent comment. You're a bad faith actor troll or a moron, I regret wasting time on this.
