If I’ve read the law correctly, here in Texas after dark if you even SUSPECT that someone is on your property intending to commit a felony level crime, you can blast away.
During daylight hours we have to follow the Castle Doctrine. Of course it depends on what county you’re in how aggressively that is enforced. Where I am I expect local law enforcement would call any dead perp a good shoot.
In TN, the local Sheriff is the law of the land, pretty much.
When I was younger, I lived way back in the mountains with a toddler. Three men pulled up but a stray dog I had taken in wouldn’t let them out of the truck. I called the Sheriff to ask if he knew who the hunting dog belonged to and he said yes. When he showed up with the owner of the dog, he asked me about the men. After I described them, he told me that if they came back and got out of the truck to shoot them dead. I mentioned the law about them being in the house first and he said to shoot them anyway and he’d have his ‘boys’ come drag them in and write a report. A lot of what happens depends on the Sheriff.
