Depends on the criminal. Some are after goods they can quickly sell - others are after guns they can use to help commit more crimes. I imagine most criminals will not consult this document, but of those who do, some will be avoiding those houses and some will be directly going to those houses.

And yeah, you risk getting shot if you just barge into a house with a strapped owner, but all you need to do is ambush him when he's going to his car, or just enter his house when he isn't at home.
