I think you really gotta look at it from the position of the guy who filed complaints finding the police chief at his house. It’s bad enough to deal with an affair; imagine finding out it’s someone in a position of extreme power in your town? What if it was a Democrat mayor? I think if it was a regular police officer they might’ve been able to let it go quietly but you can’t hide this one if it’s a town police chief. That’s a hell of a person to find your wife with and I’m not a man but I imagine it would make me nervous. It doesn’t look like he’s even fighting it either- sounds like he’s embarrassed and so is the woman. I don’t know if you’re friends with him or not but it’s pretty embarrassing I imagine for him so maybe this isn’t your hill to die on. If you’re trying to embarrass him by bringing attention to it than that is succeeding. I’d be willing to bet that he wants this to disappear and to quietly work somewhere else once his pay is finished.
