I'm wondering how they knew he had firearms to steal if they didn't know him.
Just here on INGO, I've seen more cases of poor internet hygiene that have the potential to be used to such ends than I care to count. It's not just Facebookers that are stoopid
Ding, ding, ding.
Lotsa ways to "give away" that you have firearms to steal, including the one's we really, really don't like to face. Shooting in the back yard comes to mind. Hangin' and talkin' at the gun shop or local pantry with the girls (446 & 50.)
