American citizens have the right to self defense. Deadly force is authorized. Worst case, there are a couple states that require the victim (the real one) to attempt to retreat from the attacker if that is possible. Even in those states, the Kenosha riot victim would have had the right to shoot with intent to kill. Cops also don't have to retreat, and they too have the right to self defense.
