He didnt do anything wrong - he was entirely within his rights to ask for a supervisor.
Absolutely (although they’re not obligated to fulfill the request… a lot of departments will, partly because when the stop is getting complicated they may want a supervisor to show up there anyway.) But anyway, that doesn’t absolve him of the requirement to provide an ID. He was arrested for failing to provide the ID, not for asking for a supervisor. Asking for the supervisor was a-OK, and if he’d done that while handing over his ID, he would have been fine.
You’re defining this as an illegal stop. It was not, in the legal terminology, an illegal stop. That’s part of where your confusion is coming in, I think.
I’m happy to find you one of these bodycam YouTube videos of someone failing to ID and getting their window busted out, and then look up the records and see if they actually got convicted of the failure to ID (or obstruction or whatever the statute is where they are). It may take me until later today. Would that influence you, if I found that?
