There is no such thing as excessively shooting someone. Watch any police video where they dump 100’s of rounds into a person. Training teaches you to shoot till they stop moving.

Just a little aside note. You ever play paintball or airsoft? When someone on the other team pops up next to you, you WILL turn and shoot them. You’re going to pull that trigger as many times as you can until that persons hand is up yelling, I’m out I’m out I’m out. Adrenaline is a bitch. You’re not going to think clearly for at least a few seconds. There’s no such thing as, well I got him once so I win. You’re going to go until the threat is neutralized.
