ping for later
In general his rules will lower you chance of being a crime victim, but if you are serious about not being a crime victim
have a loaded gun, you know how and are prepared to use,in your possession at all times (whether it is legal to do so or not).
I would say the exception being if you live in an area similar to where I live, with a population of 75k+ and averaging less than one stranger on stranger murder per year. In that case I think the danger of accidentally killing yourself or a family member tilts the scale in the direction of not carrying.
