If I needed to keep a gun in every room...I'd move to a better neighborhood.
I have one loaded gun at hand and I can get to it quicker than my door could possibly be kicked in short of a SWAT team coming after me. I don't live on the ground floor so there's only one way in. Everything else is locked in a safe.
I don't want to come home or wake up or come out of the shower and find myself staring down the barrel of one of my own guns that I didn't lock up.
