IMO, comparing CC or OC to police officers is probably not an exact correlation. I am a firm believer in OC. Not for the fact that it may be safer or not safer than any other form of carry, (even though I feel that there are some strong arguments either way) but just the simple fact that it a very basic right that is being assaulted from many corners in today's society.
I currently have my CC permit, but sometimes have a nagging feeling that I have just asked permission from the nanny state to allow me to exercise my basic right to keep and bear arms. If we get used to the fact that we have to ask this permission, take the courses, follow the proper processes, file the right paperwork, wait for the call, then carry the proper documentation, etc, then how easy is it going to be for the powers that be to take that away?
When I open carry, I feel that I am taking responsibility for my safety and the safety of those around me without having to ask permission of anyone to exercise my right.
