I watched a little over 15 minutes of this video before I stopped.
I have worked in the criminal justice system here in the United States for a little over 17 years with the last 8 directly in the criminal courts system. Based on my training, education, and experience here is my take on this video -
The title seems disingenuous, but I give the speaker the benefit of the doubt for this important reason; he has only been a criminal defense attorney. There are a few criminal defense attorneys that have "drunk the kool-aid." They really believe that the police are out to lock everyone up and everyone is truly innocent. The speaker seems resemble that description. As a side note, if you are ever in need of a criminal defense attorney, I would look for one that has previous experience as a state's prosecutor.
A better, more accurate title to this would be "Never Talk to the Police if you are a Suspect". I would agree with that statement. I also agree with the statement made that it has never helped a suspect's case, if he is charged, to give a statement. Yes, that statement will always be used against you. Even if it your statement is "I do not wish to make a statement."
Lastly, this video has nothing to do with report crimes. In many states here in the U.S., it is actually a crime to fail to report a felony, which any sex crime involving children is. In my state you can be sentenced up to 1 year in the county jail for failing to report a felony.
