“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 book as a gift to young people as they prepare to start their career in Law Enforcement.”

“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.” April, 2008

“I've just finished 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 himself 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.”

Coleen Rowley, Retired FBI Agent and one of Time Magazine's Persons of the Year in 2002, has to say:


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 the code’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.

Michael W. Quinn's new book, The Police Code of Silence, Walking With The Devil, what bad cops don't want you to know and good cops won't tell you, is a must read for every ethical person with the legal system.

"I found your book absolutely fascinating. It was the best book on the topic I have read. The stories were riveting, the analysis and research excellent, and the relevance to policing right on target."

Steve Lewis, Senior Law Enforcement Consultant, California Commission on Peace Officer Standards and Training


"It's a good, fun read that gets to the heart of dealing with issues of mistrust of the police in our communities of color. I would recommend it to any one who is interested in such issues, or who is attempting to deal with them. If I were teaching our Police and Community course, it would be required reading in that! "

Dr. Scott Magnuson-Martinson, Chair, Sociology, Anthropology and Law Enforcement, Normandale Community College


"Walking With The Devil should be considered required reading for all police academia curriculums, and is highly recommened for anyone who is "on the job," as well as an essential reference for civilian review board members and concerned members of the general community."

James A. Cox, Editor in Chief, Midwest Book Review July, 2005


"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 will be looking for oppotunities to make use of your book in my work with both police agencies and law students."
