So the robbers rounded the home owner and the rest of the folks in the house (according to the TV coverage) into a room... that contained a shotgun. LOL! Bad luck, robbers. Good job, homeowner!
Now, I don't know about you, but when I hear about a home invasion where the bad guys herd the residents of the home into one room, I start thinking execution. At the very least, they're getting everyone in one place, which means they're planning something IMHO. Pretty ironic that they chose the room with the gun
I don't think the invaders were thinking about anything more than robbing, necessarily.
A big tactic of home invaders is to round people up and put them in a windowless room with no phone. Like an interior bathroom. That way, one guy can watch that door, containing the residents, while other/s go about their business rounding up the valuables. Then they can slip away when done.
You DO keep a firearm in your bathroom, don't you? And all other windowless/phoneless rooms? JayG may have enough firearms, but he also has young kids and friends of kids that use the bathroom unsupervised.
Perhaps a single-gun safe under the sink in the bathrooms is in order. Something like these, which I use. For people that are afraid of guns, an old cellphone, charged, may be a good idea to have stashed. They are supposed to work for 911 calls only, if you don't have a calling plan for that old model.
