What people are saying . . .


I’ve just finished reading a great book recently written and published by retired Minneapolis Police Officer Michael W. Quinn, a brutally frank expose of the “police code of silence” entitled Walking With the Devil (subtitled “What bad cops don’t want you to know and good cops won’t tell you”). Unlike so many police chiefs who like to gloss over the strong pressures and really difficult ethical dilemmas that result all too frequently in police officers. (Even the good ones) doing the wrong thing. Quinn exposes and unravels them, through a number of true stories, many of which the author participated in. Not only is the book a must read for anyone in law enforcement, but I believe it contains a lot of applicability to ethical dilemmas in all sorts of other professions and life situations.

Many people can never understand why a battered spouse doesn’t just leave. I’ve written about that and understand it. But until I read Walking With the Devil, I never understood how a truly good cop could abide by, even embrace, the code of silence. I have written about thecode’s existence but never fully grasped how and why it exists. Mike Quinn has made a tremendous contribution with his “must read” exposition and explanation of this destructive phenomenon.”

I just finished reading your book last night. It was fantastic, fantastic, fantastic and should be required reading for every officer. My compliments to you on having captured so perfectly the complexities of the issue of the Code of Silence. Take care and, again, my thanks for this outstanding book.

I firmly believe that Mike Quinn’s book should be mandatory reading for all recruits attending a police academy and on the International Association of Chiefs of Police professional development reading list. Whenever the opportunity presents itself I give this as a gift to young people as they prepare to start their career in Law Enforcement.

Walking With the Devil examines the dynamics of “Code of Silence” and should be required reading for everyone embarking on a career in law enforcement. Mr. Quinn’s insightful examination of this topic is engaging and dispels many of the myths surrounding the phenomenon of Code of Silence.

Michael W. Quinn is a retired Minneapolis Police Officer who is determined to bring to the attention of the public an informed and informative expose of what he calls the “police code of silence” in his book Walking With the Devil: What bad cops don’t want you to know and good cops won’t tell you. Deftly edited by Margot Willet, Walking With the Devil reveals why this police version of “Omerta” comes about and is enforced by the dangers of the job and the (sometimes misplaced) loyalties that arise from them. From training in a police academy, to the investigations of Internal Affairs, to scandal driven precinct shake ups, [Quinn] lays out everything in language and example that is accessible to the non-specialist general reader. Of special note is the section devoted to ten myths about policing which range from “street justice teaching people a lesson” to once being a part of a police “Code of Silence” you can’t extricate yourself, to the necessity to be macho if you want to be effective in law enforcement. [Quinn] does more than just outline and document problems, he also offers advice for police administrators and line officers as to what can be done to weed out lawlessness from law enforcement. With the inclusion of a Glossary, References, and an Index, Walking With the Devil should be considered required reading for all police academia curriculums, and is highly recommended for anyone who is “on the job,” as well as an essential reference for civilian review board members and concerned members of the community.

I finally found the time to read your book, Walking With the Devil: The Police Code of Silence. I thoroughly enjoyed it and want to thank you again for sending me a copy. Your many accounts of your own career sparked a few flashbacks from my own. Although I did not work anywhere near as long as you did in street policing. I couldn’t help reflect upon the truth of what you said: that the code of silence challenges nearly every police officer, quickly and repeatedly. I respect the courage it took to write this book as well as the courage to deal with the devil over the course of your career. I will be looking for opportunities to make use of your book in my work with both police agencies and law students.

Michael Quinn writes a courageously truthful book on police ethics in Walking With the Devil From a practitioner perspective, his book examines his experience during his career with the Minneapolis Police Department. As we enter the 21st Century, the book should be a “Rosetta Stone” for practitioners in Policing a Free Society whether from Baghdad to Bloomington. The book is an excellent resource for academia and instructors in the field of criminal justice.

Quinn’s book reveals what really goes on behind the scenes. I learned stuff I never knew, including about one case I handled in the grand jury. Quinn describes police falsifying reports, committing perjury, and covering these acts by the “Code of Silence.” It’s cover your partner’s ass, because next time you may need the partner to cover yours. When Quinn saw misconduct, he went to superiors, first line supervising sergeants, lieutenants, and even deputy chiefs, getting no satisfaction. So, what’s so important about this book? It is that every judge should read it and understand the pressures and motivation that foster the police misconduct that defense lawyers see every day. Let’s face it, these judges are incredibly naïve about police misconduct. They think the police tell the truth and defendants lie.

When I was a third year law student doing a prosecutorial internship I was assigned a marijuana possession case. The defendant was arrested in his living room and the police found the pot in the bedroom. This was just after the Supreme Court decided Chimel v. California in which the court said a “search incident” was limited to the arrestee’s arm’s reach. When I told this to the cop who seized the evidence, he said, “Well, then, I found the pot in the living room.” Needless to say I was shocked at his readiness to commit perjury and dismissed the case. Quinn details case after case of this sort of thing.

Quinn makes the point that “one cop” can make a difference. He cites examples in which misbehaving police were told by coworkers to stop. The misconduct would stop in front of the complainant. Color me cynical, but who knows what happened elsewhere. Read this book and pass it on to the bench. It is a rare glimpse at a world that is indeed shrouded in the “Code of Silence.”

I thought I would take today to tell you that I think you have written a great book. It is sorely need in the law enforcement community. Its greatest value is that it will generate heated debates and offend those who need to be offended. I always liked and admired you. I appreciated your drive and competency. Today I admire your courage!

Quinn challenges ethical officers with a simple, practical strategy for confronting an unethical environment. Walking With the Devil instills a sense of hope for cracking the blue code of silence. I recently referenced Quinn’s concepts as I taught police ethics to the command staff of a police agency in a developing country. Without a doubt, Quinn’s message is universal. A powerful read for those who believe in the ethical obligations of the police.

Chief Frank Kaminski (ret), Evanston, Illinois Police Department



I just purchased, read (in one sitting), highlighted and footnoted your excellent book on the Police Code of Silence—I found absolutely nothing therein, with which I did not completely agree! I retired as Chief of Police for the city Bellevue, WA (a twin city of Seattle somewhat akin to St. Paul and Minneapolis). To me the great mystery of law enforcement has always been why 98% of our police officers do a difficult job well but will cover-up for the other 2%, with whom we would all be better off without—Mike Quinn has helped to explain why and how that occurs. Congratulations on an important statement that should be required reading for every Chief of Police, Prosecutor, and Judge in the United States.
