As was stated a few posts below yours, it just gives the officer more info. And as the Ohio CCW holder said sometimes it causes the officer to show a little leeway. I'm also a CCW holder in AZ and most police will ask me if I'm carrying and then ask what I'm carrying. Some get real jealous when I'm wearing my Sig 229 or Kimber.:)AWB
I read Crim's post with interest. What I got is that Ohio doesn't have the same law regarding informing the police that you have a CCW that AZ and MI do. It seems like the polite thing to do, and I'd likely do the same, except they already know. What I'm against is some curious cop seeing that you have a permit just because he ran your plates. There are a few officers here in MI who just don't like us plebes having the right to be armed, and show it.
