> Does the video also bring examples, where it was bad to talk to the police, when you were in fact innocent?
Yes. It's much closer to the end of his talk where there is an erroneous contradicting witness and you can wind up convicted of lying to the police.
He also points to things like "Possession of a lobster can be a felony". You simply can't know all the laws, so getting a lawyer forces the police to narrow the scope immediately. At that point you can address the actual charges rather than letting the police fish through hours of your babbling hunting for something to hang you with.
> When I have done nothing wrong I don't want to need a lawer by design.
That's fine. But "Shut the hell up" remains good advice. The only benefit to "cooperating" with the police is at SENTENCING. And, if I'm actually innocent, that's a bit of a problem, no?
