You guys do realize that break ins do not always happen while you are asleep? In any scenario I don't feel a locked gun is good to count on for defense though.
I agree...you should keep one in your hand and ready for action at all times. Not only does this take care of the burglary concerns, but ding-dong-ditchers, beware!!
I would rather replace stolen items than have the picture of shooting someone in my home and a giant blood stain on my carpet for the rest of my life.
A little hypnosis, a little Stanley Steemer, and life goes on. Not for the burglar, obviously, but that's what Mr Blood Stain on the Carpet gets for wanting to pilfer your fukkin' Playstation.
