There is , notice "is" not was, a retired KCPD vice cop who knocked on a few ladies doors flashing an older KCPD badge. He had taken a deputy dawg job with a local small town force back then but obviously wanted to "stay in the game". Along with ladies he used his badge to "investigate" hobbyists as well. I'm sure a few ladies left town because of him, at least one retired. Never heard of any guys taking any protective measures.
Somebody found out that kind of thing is a federal crime and let it be known in a subtle way! Oooops! That put a stop to that bull shit! I'm sure he saw his retirement check float away in his dreams!
