Lawyers of the board, is this sound advice?

Not my expertise, to be honest (I don't do criminal law), and also, frankly, not my style. I'm sure there's a basis for most of it, if not all of it, though.
I don't do criminal law either. However, being an antagonistic prick to a cop that pulls you over for a traffic violation (my characterization of what they advised in the second half of the video) is a terrible idea that's likely to you you in worse hot water than you already were (there are countless videos on YouTube that illustrate this). Somewhere around 15 years ago, I made a right turn on red at an intersection that had a sign that said no right on red. It was an intersection I'd driven through tons of times in the past, and I'd never noticed the sign. The cop pulled me over and explained why. I asked, "is that a new thing?" and he said it had been like that for years. I chuckled and said, in a
mea culpa tone of voice, that I'd never noticed it. He then let me go with a warning (the ONLY time that happened in my 35+ years of driving and having been pulled over well over a dozen times (mostly in the first few years after I got my license)). I'm confident that, had I acted as these clowns advised, I'd have gotten a ticket.
All that being said, if you're in the world of actual crime, exercising your right to remain silent is rarely a bad idea.
