I have a leopard print stun gun! The reason I have it? Because I read this website & my father is retired LE.
I'm not making excuses because I wonder myself why they had a stun gun but they might be more common than you think! My MIL has one too because she is disabled and home a lot by herself.
I heard that the biggest deterrent to break-ins is dogs. If I had my own home and lived alone, I would have a big dog or two. When they asked guys in prison who were notorious for break-ins, they said they didn't care about alarms or anything else -- just DOGS. If the house had a dog, they would pick another house.
