Biography and Publications






I'm excited to announce that I have contracted with Black Rose Writing to publish my debut thriller novel titled, STINGER: An International Thriller. The book's launch date is March 14, 2024. The back cover blurb will be something like:

In 2003, the U.S. is about to invade Iraq to search for weapons of mass destruction unless a determined CIA Intelligence Case Officer, June Cohen, can assassinate Saddam Hussein beforehand. After setting up a long-time Los Angeles based DEA Confidential Informant, Robaire Assaly, to take the fall for her theft of a Stinger right under the noses of the hapless FBI, he is now on the run. The FBI and the DEA frantically search for the stolen Stinger AND the missing informant who is now an international fugitive; however, June finds him first before he can reveal her involvement to the Feds.

I will post updates and the book's cover when available. The hardcover, paperback, ebook, and audio versions will be available at, Barnes and Noble, as well as prior to the launch date.

As a retired Supervisory Special Agent for the Drug Enforcement Administration (DEA), and a retired Chief Warrant Officer Five/Special Agent for the U.S. Army Criminal Investigation Command (CID), Gregory D. Lee's expertise covers the entire law enforcement spectrum. He is a federal and state court qualified expert witness who will thoroughly review both criminal and civil discovery material and provide his clients with a comprehensive written case analysis based on his 40-years of law enforcement experience. His specific areas of expertise include police procedures, informant handling, deadly force, use of force, arrest procedures, raid planning and execution, undercover operations, physical and electronic surveillance, money laundering, drug identification, clandestine laboratories, terrorism, and investigative procedures, to name a few.

As a criminal justice consultant, he provides a wide range of consulting, training, and expert witness services for the legal community and law enforcement agencies. He participated in a complete assessment of Saudi Arabia's drug enforcement organization and made specific recommendations on human capital management, governance, best practices, operations, intelligence, equipment, operational support and training to make it more efficient and effective.

Mr. Lee does contract instructing and has provided law enforcement training for various police departments around the country and the world.

On January 6, 2012, "Chief" Lee retired with 40-years of active and reserve service from the U.S. Army Reserve as a Chief Warrant Officer Five/Special Agent with the U.S. Army Criminal Investigation Command, better known as CID. He spent his last year in the army on active duty on special assignment as the law enforcement subject matter expert for the Special Operations Command Europe J2 (Joint Intelligence), Stuttgart, Germany. He was deployed to Afghanistan February - April, 2011 to evaluate the Rule of Law Counter-Insurgency strategy and created a comprehensive training curriculum designed for the International Security Assistance Force, Special Operations Forces. He was awarded the Defense Meritorious Service Medal for his contributions.

Greg literally wrote the book on drug investigations. He is the author of Global Drug Enforcement: Practical Investigative Techniques, published by CRC Press (2004). Prentice Hall publishes his other two books, Conspiracy Investigations: Terrorism, Drugs and Gangs (2005) and Practical Criminal Evidence (2006). At the invitation of the U.S. Military Academy, West Point, NY, he wrote "The Global Drug Trade and its Nexus to Terrorism," which is chapter 11 of Volume II, Part II, of Countering Terrorism and Insurgency in the 21st Century: International Perspectives, Praeger Security International/Greenwood Publishing Group, Inc. (2007). Throughout his DEA career he wrote numerous articles for professional law enforcement publications.

He was the last Resident Agent in Charge of DEA's Karachi Office, and lived and worked throughout Pakistan between 1994 and 1998, experiencing terrorism first-hand. The office finally closed after it became too dangerous to continue operations there, even for the cowboys of DEA. In 1995, while assigned at the U.S. embassy in Islamabad, he directly participated in the arrest of Ramzi Yousef, the mastermind of the 1993 New York City World Trade Center bombing, collected vital evidence and later testified at his trial. At the time of his arrest, Yousef was plotting to destroy 12 U.S. airliners simultaneously over the Pacific Ocean, which would have caused the deaths of over 3,600 people, more than that experienced on 9/11. He appeared on the Discovery Channel's documentary show, The FBI Files, concerning his contributions in the arrest of Mir Aimal Kanzi, the lone terrorist who murdered two CIA employees outside their headquarters in 1993. While in Karachi, he was involved in the initial investigation of the murders of four U.S. Citizen employees of the United Texas Petroleum Company, and their Pakistani driver, by terrorists.

Mr. Lee has also appeared on BBC World News TV, CNN Newsroom, with Don Lemon, Larry King Live, the Fox News Channel's On the Record, with Greta Van Susteren, and MSNBC's Meet the Press Daily, with Chuck Todd. He is a frequent guest on radio talk shows and television newscasts, and has been quoted by numerous domestic and international newspapers and magazines. His unique experiences in Pakistan are mentioned in two best-selling non-fiction books: Unholy Wars, by John K. Cooley, and 1000 Years For Revenge: International Terrorism and the FBI, by Peter Lance.

Greg's last DEA assignment was at the Los Angeles Division as the Coordinator for the Organized Crime Drug Enforcement Task Forces Program.

Prior to his assignment in Pakistan, Greg was an instructor at DEA's Office of Training at the FBI Academy in Quantico, Virginia where he trained many domestic and foreign law enforcement officials around the world.

In 1990, he was a counselor and graduate of the 160th Session of the FBI National Academy.

He has guest lectured for the Department of Law at the United States Military Academy, West Point, the Defense Intelligence Agency's Joint Military Intelligence Training Center, Washington, DC, and the Department of Defense Executive Management Development and Training Program, sponsored by The George Washington University's Elliot School of International Affairs, Washington, DC. 

In 2005, Mr. Lee was selected as the Lead Instructor for the U.S. Department of State's Antiterrorism Assistance Program’s 9-week "Preventing, Interdicting and Investigating Acts of Terrorism" course conducted in Islamabad, Pakistan. He last visited the Northwest Frontier Provence of Pakistan in 2007 when he trained Pakistani police in operational planning.

"Greg Lee has produced the textbook on drug enforcement operations. . .I strongly recommend this book to anyone involved in the field of narcotics enforcement, be they agent, detective, or supervisor."

Gary Edgington, Special Agent Supervisor, CA Department of Justice, and Former CA Bureau of Narcotic Enforcement Agent (Ret.)


"Best discussion on grand jury activities I've ever seen in such a book for professionals other than law books."

- Prof. Ralph Garris, University of South Carolina

"I really enjoyed reading Chapter 5 and thought the author did a great job of explaining the exclusionary rule and how it was developed from the three cases of Weeks, Wolf, and Mapp. The chapter was very easy to read and should make this judicially created rule easy for students to grasp and understand."

- Prof. Steven Christiansen, Green River Community College
