And how would they know I was a cop? When I go (or went) on Havasu, Mead, Mohave, Powell, or back on the Delaware River, or Ala Moana Harbor, or any of the dozens of other places I boated, who knew I was LE? Actually no one.
And the times I have been stopped on the highway (there has been a few) I'm courteous and have only been cited once. (Gardnerville, NV by NHP) I keep my badge in my wallet, out of view and don't flash it. It doesn't (or at least didn't) make any difference when I stopped one, so I never flashed mine.
And I've arrested or cited Coast Guard members and cops. The only difference between them and anyone else, was that I made a call to their command or Agency if they badged me and/or wanted special favors. I was actually less inclined to do favors, since they knew better.
What about "professional courtesy" I've always wanted my mom to use that one for me [emoji4]
