There was a case here in MN a few years ago that perfectly illustrates this point.
A guy was having problems with burglaries in his home. So…he made it look like he wasn’t home; guy broke in, he shot—but didn’t kill—him. Few minutes later, burglar’s girlfriend enters home. Shoots but doesn’t kill her. Both are incapacitated.
So far—clean shoot, imho, and by MN law.
Then, after taunting them for a while…
Yeah. He was recording this.
Anyway, he shoots them both in the head.
And then calls the cops…the next day. After consulting with his brother.
He’s rotting in prison on two life sentences for 1st degree murder, and, imho, rightfully so.
