I know plenty of police officers here who have every reason to take self defense seriously. But I don't know any that carry a firearm around the house with them openly or concealed.
Interestingly enough, it was a TX state trooper that first started me thinking about being armed at home.
I think some can get preoccupied with crime and the fear of it.
Actually for me, it's more of an "It's so easy to do that it makes no sense to NOT do it."
Also, when I compared carrying in public to carrying at home, I came to a number of realizations.
I've spent a lot of time and money so I can legally carry outside my home. I can carry for free inside my home with no legal hoops to jump through.
In public, I have to conceal. It's not particularly comfortable and it's can be inconvenient at times. At home I don't have to conceal if I don't want to and I can carry OWB which is more comfortable.
When I'm out of my home, my best option is nearly always retreat, not armed resistance. And there's usually not much that I care about around me when I'm away from home.
At home, retreat isn't really a good option and all the things I care about are around me.
In public, I can shout for help and there's a good chance someone will come to my aid. At home, if I'm taken prisoner, the odds are that no one will no until it's too late.
