Did you say that guns don't need to be stored in a safe if you lock the door? OK, I'll add windows locked too.
70% of burglaries are residential break ins, dummy. Doors and windows simply keep the adventitious thief out. Burglars love idiots like you who don't lock up their guns, which sell easily for high prices on the black market.
I don't own a gun. What do they cost? A grand for decent one? Maybe 600 bucks? Would you leave 600 bucks sitting on the kitchen counter and then leave for the weekend? Dumbshit.
