Yep. You have to tell them your name and ID yourself, you have to get out of the car if they tell you to, but you don't have to say shit about what did or didn't happen. Even if you haven't been read your rights there are still some circumstances where the bodycam can be played and used against you in court. It only takes 2 seconds for one random thing to come out of your mouth that you can't take back that can perfectly make the case against you, and put you away.

The cops' job is to catch bad people and put them away. That is fine, you don't gotta be hostile or deliberately make everyone's day unpleasant, but if you're in the crosshairs as a potential bad person don't say a goddamned word until you talk to a lawyer. Anything helpful for your side about you talking to them will still be helpful after you talk to a lawyer.

For as much as I don't agree with him stealing, this guy actually shows a great example of how it works (all sides - the manipulation of dude-just-be-honest and his correct response to it; obeying all the lawful orders but telling them to GFY whenever they ask him questions.)

"I'm not admit to a god damned thing. Prove it."

(Honestly I wouldn't even say that much, because they can maybe play that in court and say see he knew he was guilty. Just, I don't want to talk to you about it until I talk to a lawyer first.)
