When interviewed, people who are known “home invaders” say the best deterrents to home crimes are:
#1. Adequate lighting and
#2. A dog “inside” the house. And, perps are really hesitant to break into a house where they hear TWO dogs barking. They figure they might be able to handle one, but, not two at the same time.
This is on the front of the house.
The looks on the strangers' faces is priceless.
