If he’s actively trying to break in, I will take his head clean off his shoulders. I am also quick to pull the switch, if somebody is convicted of a crime.
However, if the person becomes incapacitated, unable to continue his crime, the only thing I can do is pull up a chair (close enough, but not too close), point my gun and call the cops.
If he stays still, he lives. If he attempts to move, he dies.
You breach my home or business buddy... you might die.
