I just finished both parts, it's really awesome.
The first half is a criminal defense lawyer, and his take on 5th amendment right and all that. He's very well educated, and he knows the stupid things people do that get them convicted, and how cops use simple mistakes.
The second half is a cop who's performed thousands of interviews (aka, "interrogations") in his life. He tells stories about how people convict themselves, and how pretty much everything the lawyer said is true. He talks about a lot of the techniques he uses, and some of the craftier tricks (like using a fake tape recorder, turning it off, and saying "this is off the record" -- there's no such thing as "off the record").
Both halves are very revealing, and totally makes me rethink how I'll react if I'm ever questioned as a suspect.
