The Author developed the Lewis Rules through thirty years of Policing in the toughest Police Divisions and areas of Toronto, Canada. These rules have been taught to many police officers across Canada. They are just additional guidelines for being on the street with police officers and criminals. Some are just common sense; others come from experience. Some are from mistakes made during the policing process, and others are just plain advice. Detective Tanton W.Ryan navigates these situations as he makes his way through a storied career in the great journey that is Policing.They just called him Ryan.
