Yes I do and not 100 percent of the time. I do not carry at home and I do not carry running. Yup, 100 percent of home invasions happen at home and yup, 100 percent on joggers happen to joggers. But here is the deal. Instead of playing out every scenario imaginable (which I stated I do not care what others do) I do a risk assessment. The odds of a male jogger being assualted are so low it is ridiculus. Now of course folks will at this point bring up that it does happen. But seriously, I weigh the odds of being assualted running vs the weight and discomfort of carrying (I run 8-22 miles a day depending) and I choose not to carry. I am also real good at H2H.
But you carry a gun, right? Always or just 50% of the time? And yet the probability of you needing a gun for SD is astronomically small, yet you carry one.
Of course you have to look around you and stay abreast of what is going on in the world. But that does not mean I check out every single person I meet and assess if they are a danger. (OK, sub conciously we all do...we are more leary of a begger in an ally than we are a man in a suit in an office). But that is just normal SA. I really don't give a hoot abut random events. You do not know what is going to happen, when it is going to happen, or the conditions of which it might happen, and the abiility of your foe(s).
But, SD advocates base their decisions on violence in America, even at places like Lowe's, Walmarts, schools, churches, in the car and in the home, etc. That's not paranoia - that's responding to real events.
