So, there's a new book out from James Duane. Who is he? He did the "Don't talk to the police" viral video.
https://www.youtube.com/watch?v=i8z7NC5sgikA police officer refuted him with "Ayep. Everything that guy said. Actually, it's a lot worse."
https://www.youtube.com/watch?v=08fZQWjDVKEThe police officer was very comfy stating so, because as he says, most criminals are stupid. They talk themselves into prison, all day long. The video was pretty good, on both sides. But times change. Mr Duane wrote a fairly short but excellent book that is a necessary update to his classic video. Like the overwhelming majority of police, he firmly believes that he only puts guilty people in jail. Unfortunately, being innocent isn't always enough of a defense.
Thanks to the hardwork of the Department of Justice, there's some fairly modern changes.
1. Pleading the fifth can be a sign of guilt now. Don't do that. Plead the Sixth.
2. You don't actually have a literal right to remain silent, only a metaphorical one. Physical silence can be held as a sign of guilt now, per Salinas v. Texas. You must formally invoke your right to silence.
3. Grammar can get you into prison. Be very very very careful in how you invoke your rights.
4. Remember, the cops can lie to you. You cannot lie to the cops.
etc, etc.
It's a really good book and well worth the read. Covers a bit on taking to feds vs talking to the police. The lawyer goes over when to be a reasonable person (always give your name and what you are currently doing at exact second if asked) and when to lawyer up (virtually any other time). Is it overkill? Probably. He was a defense attorney. It's short. I picked it up on kindle unlimited for free, otherwise $6 for the ebook and $10 for the paperback. Worth every penny.
