We already know there's more to it than that. The homeowner was punched in the face, and the two lefty nut job idiots tried to break their door down.
Yes,I didn’t see that at the top of this thread. If there was a wheelbarrow involved and that wheelbarrow was used in an effort to break down their door then,IMO,it stops being “murder” and,perhaps,becomes “unauthorized discharge of a firearm”.
