Let’s assume your house has been burglarized once. A common assumption is that they got everything they came for. You may be a little more careful about locking your doors and windows and hiding whatever they missed but do you think they will come back?
Imagine arriving home from work to your front door wide open. As you walk toward your home, you see there was clearly a forced entry. You enter your home to find your TVs, computers, and jewelry missing. You have no idea how long the intruder was in your home. You call the police.
