Involved.
I shot your friend outside the house not long before because he came to the house unarmed, locked it and took guns. You would've seen his body outside. It was obviously still not safe.
I think that for your own safety that if you don't see their hands you should be able to shoot them. Often people have pistols in their hands, but their hands are behind a barricade and you have no clue if they're about to shoot you or not.
