I think the evidence is that the culture is changing, with some still holding onto the old culture of ignoring misconduct and others now prepared to report it. It was never going to be the flick of a switch.
I bet you some workplaces have people whose conduct is dreadful and others where there is zero tolerance to anything. I am sure most places are like the police, where some people live charmed lives and get protected and others do something minor and get the book thrown at them.
I do not believe the police is an outlier when it comes to workplace conduct and discipline.
