Hey, it's NPR's Book of the Day. I'm Andrew Limbaugh. Okay, kind of a heavy topic today, but a really important one. It's the brutal treatment of the Uyghur Muslims by the Chinese government. In a bit, we'll hear from an attorney whose new book details what life is like inside the prison camps where the Uyghurs are kept.

But even outside of the prison camps, in their regular day-to-day lives,

Uyghur Muslims in China exist under constant surveillance.

Investigative reporter Jeffrey Kane put out a book last year titled The Perfect

And he tells here and now Scott Tong that this technology made with the help of American companies

is now being exported across the world.

helping you understand why distant events matter here at home.

Listen to sources and methods on the NPR app or wherever you get your podcasts.

In the six years, we've been conducting our little experiment.

There hasn't been a single murder.

And now pre-crime can work for you.

We want to make absolutely certain that every American can bank on the utter infallibility of this system.

Opponents worry this system could arrest innocent people.
