If this goes to court, the discovery would be interesting. Exhibit A is the finger in the glove, to match up with the accused who has a severed finger.
That’s the problem: the accused DOESN’T HAVE a severed finger. Unless, of course, it got sewed back on. In which case maybe they have to match the stitches to the dent in the door?
So a guy with a gun comes running across the yard yelling “let me in.” Slamming a door seems like a good first move. Getting ones own gun out of the umbrella closet would be a good second move.
