But he found his gun in a pitch black room didn't he.
Not really been following much but where was the gun kept.
Erm, if you kept a gun for defensive purposes, wouldn't you know exactly where to find it at all times? That's the whole reason why you'd have it in the first place, it would be pretty silly if you weren't able to find it even in a dark room. I can find my torch at night if I need it, I can almost always pick it up as I know exactly where I left it. It doesn't take a criminal mastermind to be able to do the same.
