Don't Talk to the Police (2012)

Because talking to them on even the smallest matter can land you in trouble, since lying to federal agents is a crime.

TurboTax has this audit defense insurance add-on when you submit your taxes. If you read the verbiage, it explicitly states DO NOT answer any questions under any circumstances, and defer them to the audit defense. Don't even answer "How is the weather over there?"

It's best to have some representation when dealing with the IRS or any federal agency. As the video continues on to show, Martha Stewart was convicted for lying because she decided to talk first and deny involvement before lawyering up.

I watched the video and read some background, basically my understanding is that the entire series of events went like this, at a high level:

The guy in the hotel room had been showing someone his pellet gun. Someone saw this through the hotel room window, thinking it was a real gun, and called the cops.

The cops arrived, expecting someone armed and dangerous. They seem really amped up on adrenaline.

A woman and the man come out of the hotel room, and the cop with the assault rifle screams at them to get down on the ground. They comply, but seem scared and confused. The cop asks if they are drunk, which they deny. He asks if they'll be able to understand all his commands, and they say yes. He keeps screaming at them and cutting them off when they try to talk.

The woman follows instructions and is successfully cuffed and taken away. The man tries to comply, but is sobbing and appears drunk. The cop gives him some (what seemed to me) not entirely clear instructions, and then tells the man to crawl toward him. After about 5 feet the man seems to lose his balance and try to pull up his pants, at which point the cop repeatly shoots him.

At the end the two cops try to get in to the hotel room, but the key cards they are given don't work. The second cop drops a key card after trying it a handful of times, picks it up, and keeps trying, seemingly extremely agitated. The video then cuts out.

The link doesn't explain anything about his argument except that it's in his book. What does "say little" entail and why does he recommend that?

Also, from the context it seems to be about what to do after a self-defense shooting - is his advice specific to that context, or a general argument?

It's a good way to find out if they were lying when they said you aren't a suspect. You should ask for it if their claim is that they want to talk to you about someone else's behavior. If they want to talk about your behavior, find a lawyer.

He also gives several very clear examples of why this is the better course of action. Skepticism is good, but this is like looking for hidden motive when your doctor tells you to not swallow random pills without consultation.
