I had a home invasion while I was at home back in the late 1980s. I did not have a dog at the time, but I had a Charter Arms Bulldog 44 spl that came so close to barking at partial trigger squeeze when the person saw it and turned and ran out of the damaged front door.
I had my home broke into in Cal while I was out with my neighbor at a local store. Came back to her place looked over at mine and noticed the patio door was ajar. I knew someone had broken in very recently. Grabbed my gun, told my neighbor to call police and tell them someone forced entry into my house. I ran in the front door and saw the guy exit the out the back which was one level below. It was in the 70s before Cal went nuts.
When the coppers got there, I noted nothing was missing. The copper, for professional curtesy, said was probably the druggie on the next block who was just released from jail for assaulting his mom.
Rumor has it he received a call from a pay phone telling him if he broke into a home again in the neighborhood his brains would be on the pavement. Irony, no more break ins in our neighborhood. No idea who made that call.
