unlocked door + alcohol + firearm = tragedy. Old, sad story.
Not enough info here for me.
This happened to me when I was a teenager. I woke up about 7 AM and went to the kitchen to get something for breakfast. When I entered the kitchen I got a strange feeling, and I looked into the living room and saw a strange man sleeping on my sofa. I ran into the bedroom and got out my 22lr rifle. When I went into the living room I could tell that the man was drunk. I used the rifle to poke him and he woke up, and you should have seen the look on his eyes when he saw my rifle pointed at him. He said that he was looking for Sam, which is my dad’s name. He also told me that he was sorry for falling asleep on my sofa. I told him that he was lucky that I had not shot him yet and to get the hell out of my home. I never saw that man again.
The point is that I was very scared when this happened, and I would have shot this man in self defense if he made even the slightest aggressive move toward me. I would have probably found the home owner not guilty.
