D bag robber doesn't care about your opinion, semantics or the law. It's a smash and grab crime where time matters. They're going to go after "easy" and the additional step of securing a firearm in a safe, one that's not easy to get into or remove from the vehicle, is a far better option than leaving it where it's either plainly visible or in a glovebox. The law or semantics have nothing to do with it. I'm sure most of the people that had their vehicle broken into also had some sort of sticker on their back window advertising them as a gun owner. But hey, practice that first amendment.
And the whole theft was shockingly quick. They caught it on surveillance video. I'll try to find the article.
I've seen multiple restaurants also post warnings on their front door in regards to vehicle break-ins and weapons being stolen. The one I was at last night got so bad they posted the warning and have since hired security to drive around the parking lot. Thieves are also targeting cars and trucks parking at stores that carry guns and ammo like Bass Pro and Academy.
