So basically you had a robbery attempt/home invasion at your home, and realized it when you saw the bad guy(s) right there in front of you. You were carrying at the time, and were able to scare him/her/them off or hold him/her/them at gunpoint until police arrived to arrest him/her/them. Close?
It is good advice. Having guns stashed around the house, not necessarily a bad idea, but pretty unhelpful if you walk out of the bathroom and bam, criminal right there. No time to run and grab the gun you have stashed when it's in between you and the bad guy.
I mean I don't know the stats, but are you more likely to face a criminal there then you are to face a criminal trying to break in your house? I'd imagine home burglary or robbery, and home invasions about as common as burglary or robbery when you are out and about. So if you carry when you leave your home, why wouldn't you carry when you are in it as well? I do understand it can be easier to have other preventative measures in place at your home that aren't possible elsewhere, like motion lighting, alarm systems (to include dogs), locks and other reinforcements to inhibit break-in, but not everybody has those things, and even then, it doesn't prevent everything and may not even give you enough warning anyways.
Good reminder.
On a lighter note, earlier tonight my dog started going crazy. He hardly ever barks, and certainly not like this. Something was definitely up. Fortunately it wasn't anything nefarious, but it was interesting to see.
"What are you barking at! Be quie...oh, there are horses in the backyard. Good boy!"
Neighbors horses somehow got loose and decided to hang out in my yard. That was a new one.
