I have no trust in the system whatsoever, which is why I wouldn't talk to police. And I have seen that video and easily over a hundred police interrogation videos. It astonishes me how readily people talk to police and say shit that would have landed them in jail even if they were not involved in the crime they were discussing. As an autistic person, the interrogation videos with commentary and breakdowns have helped more with understanding social situations than most of what my parents ever told me.

Edit: interestingly enough, the best example of what to do when interrogated by police on YouTube from an actually guilty guy called Rocky Rambo Wei Nam Kam. When interrogated and asked about the murder, his responses are basically 'I don't want to talk about it' and 'I have nothing to say', when asked about irrelevant questions he was curt and dismissive in much of his answers.
