It’s funny that a “friend” of mine knew how to get into my house. I was in AZ and he gave and “unexpected house call” from Vegas on a saturday night all the way to my bedroom door. He was close. He was met with a high-powered rifle until I saw his face. It was 4:00AM. That was 20 years ago.
While I was away I thought of the just as important tool you should have - a good tactical style flashlight. I bet your friend remembers it just as clearly from 20 years ago too!
