I'm 28 years old. This professor in the video is a former defense attorney. The policeman is a detective. The Supreme Court justices agreed with him and everything he says is true.
It's not a "fuck the police" mentality as much as it is a "cover my own ass, I don't want to be the 1 in a million who winds up in jail for no reason".
Never speak to the police without an attorney present. That should be much more satisfactory.

First off, a guilty party going free is better than an innocent party going to jail.
Second, if someone really wants to offer help to the police, do it through a lawyer. Offer your testimony through a lawyer and make sure you get immunity.
You can help the police if you really want to, just make sure to be smart about it. Talking to them in your doorway without a lawyer present is not being smart about it.
