None of those are cases where someone was arrested for using a firearm to stop a rioter who was breaking into their house.
The first one was a crowd gathered outside the home to annoy the homeowner with loud music and lights. They never even stepped onto the guys property, no less tried to break in. The homeowner was arrested for handling a firearm while intoxicated.
The second one was a crowd passing by a home. They too never even stepped onto the couple's property, no less tried to break in. They were arrested for brandishing a firearm at someone who wasn't threatening them.

And the homeowners never fired a shot yet they had repercussions taken against them by law enforcement.

I don't know what you're trying to change your point to?
I already pointed out why they were arrested.
1. Handling a loaded firearm
while intoxicated. That's a crime in Milwaukee.
2. Brandishing a firearm against someone not threatening you. That's a crime in Missouri.
3. Shooting people. That's a crime in Wisconsin.
