Earlier quoted context omitted.
A jobsite has different and looser standards of professional conduct than what the police should be generally held to, yes.
I don’t think the cruiser is subject to your elevated standards. This is a classic case of double standards. We want one set of standards god people we agree with and another set of standards for people we disagree with. To avoid this, we institute a standard across the board for everyone, like them or dislike them.
And yes, it's fundamentally OK to hold police to a higher standard than the general public, including literal children. I'm not sure why this is in question.
