I listened to the audio book and the author starts by saying he is not writing an anti-cop or anti-criminal book rather a policy or political book.
The book is good and I agree with many things the author says and disagree with some things.
The book is essentially a history of police forces across America from the beginning of our Republic and focuses mostly on the 1950's & 1960's up to present day (2012 the year the book was published).
I selected this book because I thought it would provide some answers to the recent police shootings of unarmed civilians which has led to murder of on duty police officers and additional racial tension in our country. The book definitely provides some answers to these questions.
One of the answers is that politicians are involved and award police forces with money (from taxpayers I should point out) to buy new toys (many from the military) because of their arrest records and mostly drug arrest records.
The book also chronicles the rise of S.W.A.T. teams across the country and details many in small cities and posits whether these teams are really needed for these smaller cities.
All-in-all a good book that I would recommend that is informative.
