[snip...]Responsible OC, to me at least, means going about your business in a quiet and discrete fashion....not self-identifying and calling attention to yourself every time you see a guy with a badge.
This. Exactly this. I've not had really any negative encounters with much of anyone, and except for one day when I was in Texas, have OCd every day since Nov 1. If I see an LEO in a store, I smile and nod and go about my business. I don't bring it up with anyone unless they ask me a question. And to tell the truth, 95% of people never even notice.
