It may not be about fighting off attackers.
Imagine if this was a school campus or a kids baseball game as you're pulling up in the parking lot.

Raw bodycam from the shooting at the Allen Premium Outlets mall:
Allen, TX Bodycam
Warning: Video is blurred out. But it's pretty intense.

Having a firearm and knowing how to use it is a good start, but don't you want every advantage you can get?

That video is pretty intense, but in the end some other officer put the shooter down first. Anticlimax.

The bodycam-officer started hyperventilating around the 1:30 mark. Brave moving forward, no doubt, but he didn’t need more muscle, he needed to keep the adrenaline in check. Not easy - or possible - to do, not calling any fault on that.

More muscle is almost never the answer, see my previous response in this thread.
