I’ve actually had one inside my little cottage at about 3:00am, drunk as all get out and eating my fruit cake.
I ushered him back out the door and walked him down the alley to get him headed away from my house.
I will admit that I come on a lot of police shooting threads to question the actions of dog shooting, mental patient shooting, kid shooting etc. By the same token I expect homeowners with guns to exercise restraint. If you shoot someone you should be held accountable as the facts warrant it. Someone knocking on your door is not fair game.
As to your case of someone being in the house eating your fruitcake, I probably would have thanked him for disposing of that toxic material:) Actually in court you would have had justification and your actions indicate someone with wisdom.
