I think he wrote that book in part because he was frustrated by the lack of nuance in his presentation and the fact that it sort of "went viral". 13 million views for a lecture about law is pretty astonishing.
Professor Duane has a video on that topic.
Just out of curiosity - are you possibly confusing civil vs. criminal cases? The 5th amendment does apply in civil cases to the extent that you cannot be compelled to testify - but a judge can interpret your lack of response in a negative light in a civil setting. This differs from criminal cases where the lack of testimony is not admissible nor can it be considered in determination or sentencing.
Just thought I'd help clarify where I was coming from. That trial does seem to fit the scenario though.
And it brings up amazing cases where the system is definitely not limiting it's powers and it's leading to false convictions.
Here's a youtube of more or less the book: https://www.youtube.com/watch?v=-FENubmZGj8

EDIT: errm actually that YT video is actually a little scant on details. The TLDR is say nothing except make an absolute demand for your 6th amendment rights (a lawyer). And don't be soft about it like "maybe I can get a lawyer?" ... say "I have a right to a lawyer and will not answer anything without first speaking to my lawyer"
People might be thinking "I thought it was the 5th ?" Ironically , the same conservatives that have been trumpeting the 2nd have concurrently been undermining the 5th and now can be used against you as evidence of guilt.
