He has a point though with being singled out and shot first. I believe he is fine with OC around his place but prefers to CC in public so not to cause a commotion.
If I'm willing/desperate to rob a store and I see a guy OCing, I will target them first and eliminate a threat. Yes there maybe someone CCing but I don't know who. That is what makes CC so effective, you don't know WHO is carrying and HOW many. You can walk into a store with 5 people with all CCing or walking in with 30 people not carrying, or vicea versa. My CCW instructor prefers to CC everywhere b/c he doesn't want people to know he is carrying and the only time he wants a person to know is when they see the business end of his gun and hearing the sound of his safety being clicked off. That is why I like Glocks, don't have to worry about a safety. Just gotta worry if I ran the slide when I walked out of my house that day.
