That it took me nearly four years to eventually finish this book says something.
This was a frustrating book that tried to do too much and became overwhelming. The author tries to tell a chronological story, but he's never clear about the story he's trying to tell. It's a story about police brutality, small-town corruption, and race and racial relations in 1980s East Texas. It's a story about legal strategies and counterstrategies, protests, human interest concerns, and human collateral damage.
The author introduces far too many characters (including the setting or locales) for the reader to keep track. They may be essential to "the story" but the reader... or at least this reader kept getting lost sorting out how each character shaped the story.
