I do think that many who do carry in home are probably overestimating their situation, and they could probably live out a thousand lifetimes in their current circumstances without having ever had a home invader.
Another odds maker.
The odds are 100% that it's going to continue to happen to many who had those same wonderful odds working in their favor.
And some won't even be living out one life time---since they'll be murdered like others "protected" by the odds.
Just my thoughts on the matter.
