You hear more and more about homeowners fighting back and shooting the intruders. More and more people are becoming gun owners and one of these days, the're going to break into the wrong house and that'll be the end of them.
Remember to LOCK your cars especially if you have a garage door opener IN the car. And watch out for what you "think" is just another roofer leaving a card in your door. They may not be roofers at all and could be scoping out your home.
