Shanahan, Mike Disanza and Keith Bettinger.  With the addition of these police officers, the total number of books listed on the website that were written by state or local police officers has reached 400. 

Michael D. Lyman, Ph.D., began his career as a special agent and criminal investigator for the Kansas Bureau of investigation.  He then moved to the Oklahoma Bureau of Narcotics and Dangerous Drugs as a senior agent and criminal investigator.  While with the Oklahoma Bureau of Narcotics and Dangerous Drugs he was assigned to the Street Enforcement and Intelligence Division.  During his 11 year law enforcement career Michael has made over 600 felony arrests.  For the last 18 years he has been professor of Criminal Justice at the Columbia College of Missouri.

Michael D. Lyman, Ph.D., has authored seven books about the enforcement function in criminal justice.  His books include: “The Police: An Introduction,” “Criminal Investigation: The Art and Science,” Practical Drug Enforcement” and “Organized Crime.”

Daniel J. Shanahan’s book “Badges, Bullets and Bars” tells the story of his career on the Baltimore Police Department.  The book is billed as a “first hand account of police loyalty and disloyalty.”  Moreover, according to Shanahan he wrote the book, “for all the excellent Law Enforcement officers who shortened their careers by crossing the thin blue line and venturing into the wrong territory; sometimes into criminal territory.  Therefore permanently tarnishing their badge, reputation, family, and all the good that badge stands for. This book is for the police officers that could not find their way back, wanted to make a difference, and unfortunately, could have.”

Mike Disanza's biography, “A Cop for Christ,” tells of growing up in the 1950s and seeing the New York Police Department as a way of leaving his poverty stricken neighborhood.  The reader is taken on a journey that examines Mike’s 22 years on the job and the circumstances that led to his Christian Ministry.  Currently, Mike is the president of International Cops for Christ, an organization which has been serving the needs of police officers world-wide for 25 years.

Keith Bettinger is a retired police officer who served with the Suffolk County Police Department in Yaphank, New York from 1972-1994.  His book, “Fighting Crime With "Some" Day and Lenny: Or What Happens When Dragnet Meets Car 54 Where Are You?” follows the adventures of the fictional characters Detective Lenny Birnbaum and his boss, Sergeant Robert “Some” Day, as they fight the evil-doers in that hotbed of crime, Staten Island, New York.
