Query: Bad

This book is bad. Aside from being historically inaccurate in several areas, the authors quote newspaper clippings and "anonymous", uncorroborated, negative citizen comments as fact. The authors "preach" their perspectives and beliefs based on their "theory" of how minorities have been abused or mistreated over generations. Very little, if any, of the information presented as factual is substantiated by historical evidence. Ninty percent of the book is pure speculation, conjecture, and biased opinion against law enforcement. It is a very slanted and liberal writing. I do not recommend it unless you are mandated to read it. For a better perspective on the real world of managing in law enforcement, try Proactive Police Management. It is also a liberal slant of view, but a much more accurate and interesting read.
