Most criminals are smart enough to case a property before entering and knowing when the residents aren't home. They probably just waited for them to leave then helped themselves. Guns are stolen from homes all the time, and these morons just gave the criminals a map to their front door.
Thirty years ago when I was 22 I shared a house with a friend and had an extensive gun and camera collection. Witnesses saw a man back his car into my driveway shortly after I left for work, load up many items into his trunk then drive away. One of my neighbors got his license plate number and he was arrested an hour later, but none of my items were with him. It went to trial, and because he hid all of the stolen stuff the jury let him walk because there wasn't enough evidence. Ten years later about 100 miles south of where I lived, a man and a woman were arrested for attempted bank robbery. In the car was one of my rifles and one of my cameras. The woman was the former girlfriend of the guy they arrested for breaking into my house, but because he was already aquitted he couldn't be re-tried on the charges.
My point is, they know when you aren't home and if there is something there they want, they will get it regardless of the risk involved.
I just read the article. The editor of that paper should race some type of charges for his actions. Like Gorilla I'm all for the 1st but when lives are at stake, then there conduct must be accountable. This "gun map" has literally given any criminal a shopping list of possible weapon stashes. Lucky this gentlemen had a quality gun safe. I fear this wont be the case all the time.
