So, people troll the internet looking for gun owners who post pictures of their guns, only so they can go hunt them down in real life to steal said guns?
Makes about as much sense as using a loaded bullet to replace a blown fuse. Sure, some nut-job out there will try it.. but they'll likely die trying.
Plus... if people wanted a list of houses with things to steal in them, all they'd have to do is look on this forums "show off your gear thread", or more to the point, on the average person's facebook.
They post their new cars/iphones/tvs/computers/cameras/etc, AND they post when and where they are via foursquare, twitter, and other apps, AND post enough personal information to be able to find out where they live... and yet facebook, as a country, would be the 5th biggest country in the world by population.
