I have checked to see how my house is set up for self-defense. The door entering the house, then the door getting into my house. Yes, double door entry, it is going to slow down anyone getting in and probably piss them off having to go through two locked doors. Next to the second door is a target marked 25 shots, 25 yards, all center shots and my Marine Corps plaque next to it. If a person still makes it in my war room is double locked and I have a hidden gun safe in the wall. All the windows are on the second floor. Motion lights around the house. Alarm on balcony sliding door. Camera set up on front door that covers the front yard well. The 3-d target at the end of the hall way. Our dresser is set-up to give us cover upon someone entering our room. Girlfriend is usually at home and I work. When I come home we have our greeting that we notify all clear and it is me. Our tactics upon going anywhere I mention when we are in a compromised location, getting gas, store, or where ever I feel as though we could run into a bad situation. We train to shoot center mass and the situating yourself by the side of cover.
