I'm a librarian who loves anime, manga, and reading a wide variety of genres.
And I'm done.
I've recommended this to the Colorado Springs folks I know, and I think people (especially white people) with any kind of connection to Colorado should probably read it. That said, there were organizational issues with the text (stuff would get mentioned earlier than it should have, muddying the timeline, and some things came out of the blue, like one of Stallworth's Officer Ed rants). Also, I very much disagree with Stallworth's "Antifa" statements at the very end (he chose to capitalize the word and clearly considered it to be an organized movement).
ETA: One thing I wondered about was the legality of the book. Stallworth based the book on his own experiences and police reports that he'd been instructed to destroy. Instead of destroying them, he stole them and took them home, where he kept them for the past 30+ years.
