I have more knives than guns. House is closed quarters, so if someone breaks in, by the time they raise their arm to point their gun (or whatever) at me I would have them cut up like a chicken before they say 'shut up, don't move'. This guy is just asking for it holding that long ass barrel in that living room.
Also, why the hell is he sitting in front of a damn window with thin sheets, holding a rifle!? He's just begging for a headshot!
