This is absolutely terrible. This is a perfect example of the persecution gun owners fear when they're asked to register their weapons. We need more gun registration and exposing data like this does nothing but hinder that goal.

1) Is the house occupied? 2) Are the occupants armed?
Providing an answer to the second question only helps the criminal by letting them know that they can perform an armed robbery with no resistance.
