Agree
LEOs will stopping wasting their time, if they realize nothing will come from talking to OCers. If they believe they can spark something that leads to an arrest, I am sure they will pursue. If all they are going to get is an awkward situation caught on tape everytime they "investigate" an open carry incident, then they probably will request a disregard or make the "investigation" very quick and painless, e.g. say "be safe, and have a nice day"...
The LEO had the same "gum-pack" camera on his chest that I use for open carry... Having the handheld makes it more obvious that one is taping and allows the open carrier an instrument to focus on when ignoring questions from LEOs.
