John P. Crimmins retired after 25 years of service with the Chesapeake, VA police department. During his career John spent 12 years as a criminal investigator, three years in the Crimes Against Property Section and nine years in the Crimes Against Persons Section. Realizing that the ability to effectively illicit information from reluctant witnesses and suspects was the key to a successful criminal investigation, he dedicated himself to learning and mastering the art of interview and interrogation.

The confession rate increased resulting in an unprecedent number of case clearances for the City of Chesapeake Police Department. John has taught counter-terrorism and intelligence gathering processes to police officers in the U.S., Indonesia, the Philippines, Thailand, Chad, Burkina Faso, Guinea, Cameroon, Central Africa Republic and Niger. Additionally, he has imbedded with law enforcement officers in Cameroon, Burkina Faso and Chad to train them in various law enforcement techniques including, but not limited to, interview and interrogation. Present during the twin bombing terrorist attacks in Ouagadougou, Burkina Faso on March 2, 2018 John advised both the Burkina Faso National Police and the Gendarmerie in techniques to utilize during the interview and interrogation of witnesses and suspects. John taught interview and interrogation, criminal investigation, officer survival and defensive tactics courses, as a collateral duty, at the Chesapeake, VA Police Academy for 20 years. Additionally, John was an Adjunct Instructor in the Department of Sociology and Criminology at Old Dominion University, in Norfolk, VA for 13 years.
