You keep talking about stuff that isn’t germane. It was illegal to carry the weapon and ammo where he was, and while doing what he was doing.
People who carry guns while fighting with police while carrying guns get shot, a lot. No illegal carry, no shooting.
You specifically asked why he was carrying extra magazines.
I told you, it’s a normal thing to do.
Clearly you did not know that, which very much calls into question your implicit claim that you go about armed. You just don’t know the basics.
Try to keep up.
