About the Authors


Dr. George Kirkham is nationally known as “the professor who became a cop” for taking a leave of absence from his university post to study the police in a way that no criminology professor ever had. After attending and graduating from a police academy, he spent six months as a patrol officer on a high crime beat in a major American city. After returning to Florida State University, he continued working as both a fully-sworn police officer and a professor of criminology throughout his entire academic career. He ultimately served with four different law enforcement agencies in assignments as diverse as uniformed patrol, crisis intervention, vice & narcotics, criminal investigation and undercover work as part of an organized crime strike force.

His observations on the police have appeared in research and law enforcement journals in many other countries, including England, Canada, Germany, India, Australia and Russia.
Under grants from the U.S. Department of Justice, Dr. Kirkham’s award winning series, “Police: The Human Dimension” was distributed to the law enforcement training directors of every state and the F.B.I. Academy.

Dr. Kirkham has served as a consultant and trainer to over 50 American law enforcement agencies at the federal, state and local levels. He has been called upon more often than any criminologist in the nation to provide expert witness testimony in civil and criminal actions involving police, jail and private security issues. He has been a consultant in over 1,500 cases in all 50 states.

Dr. Kirkham described the ice-water shock of his transformation from a Berkeley educated scholar to an urban cop in his best-selling autobiography, Signal Zero, which was a Book- of- the- Month Club Alternate characterized by police author Joseph Wambaugh as “….fascinating, vividly and honestly told.” Acclaimed as “an honor to his profession” by the late William F. Buckley Jr., Dr. Kirkham has been the subject of a 60 Minutes segment with Dan Rather, as well as feature articles in Newsweek, U.S. News & World Report and People. He is Professor Emeritus at Florida State University College of Criminology and Criminal Justice.
