As with most of the other posts, I do not want to be a cop. The only reason I have a carry permit is for the protection of me and my family. This may seem heartless but I feel absolutely no obligation to defend anyone else or their property. I certainly don't need a fake badge to make me target or attract attention. Open carry is legal in Iowa and I don't want that type of attention either. I know some people open carry and that doesn't bother me. I prefer my privacy and anonymity.
I should add that I would protect myself, my rights, and my country against tyranny. I believe this is self protection.
