My daughter has rules. No running, jumping, or touching each other in the house. She has them written on a board on the wall.
When I enforce those, I tell the grandkids to read them, and tell me which one they broke.
I didn't make the rules, I enforce them. I wouldn't enforce them if they didn't make sense.
But there is ONE policy now and forever, and it's hanging on the wall for me and the grandkids to read.

But that doesn't mean you have to disclose the policy you establish, particularly if said policies would prove unpopular.
With that in mind, establishing a police presence that walks, talks, and swims like a duck would seem prima facie evidence you intend to move toward policies that require ducks to enforce them.
