I agree that a gun is a last resort and we should all harden our homes. The break-in at my house was at 3:00 a.m. The intruder tried to get in through several windows - police found evidence all around our house. When he started kicking in our glass patio door it woke us up. Modern patio doors are incredibly strong. It took the intruder about three minutes of kicking and throwing his whole body into the door before it exploded into our house and he came in. During that time I tried to dissuade him - told him police were on the way (wasn't sure but what the heck); showed him my gun; told him to go away many times - all for naught. If a large strong person is determined, he will get through your defenses. Maybe a big loud dog would have gotten his attention. Maybe not.
