Under Wisconsin castle doctrine. That's fine.Ok, so I freely admit that this still makes no sense to me. In my mind, the second you pull out a gun or weapon that is illegal/banned, then you have automatically escalated past the point of "reasonable force", due to the weapons in question being banned. Like in your hypothetical, what if, instead of going for the ghost gun, I just hock a grenade at the intruders? Or just go full Tarantino on them and fry them with a flamethrower (yes these examples are ridiculous, I know)? But again, I freely admit that I just don't understand this and have had this pointed out to me a few times now.
Yeah, like I said before, this whole thing was fucked from top to bottom right from the start.
It comes down to two separate crimes.
The crime of them entering your property illegally
The crime of you owning the illegal weapons.
They're not the same thing being looked at and using the illegal weapons doesn't suddenly negate the crime of the person illegally entering your property and doesn't negate your right to take action to defend yourself.
As a reminder, that guy opened fire on the Police who came to arrest him with claims being put out he did so because he thought the Police were there to Rob him. He's already shot a person and so they knew he was armed.
Moral of the story. Don't take pot shots at police officers from your window.
