Well personally I could care less how you carry. OC or CCW as long as you are totally legal to do so. And not just doing it for some macho fuzzy feeling! Heck I might even do it myself at times if I could. But we can not in my area. For the good or bad of it, or what ever.
But if as some of you have stated and, are on the train of thinking that they would rather be OC'ing in a SHTF situation, give this some thought too> don't you think that maybe; when whom ever decides to go bonkers and just start shooting that seeing you OC'ing a gun they might say to themselves, yo self ... that person has a gun standing over there, and once I start bangin um off they are going to start shooting at me so I think I better shoot them first!!
So there would be a good element of ... surprise !!!
