Excessive Force, False Arrest, Police Misconduct & Self Defense Expert Witness


INTRODUCTION: Professor Gregory Gilbertson was a police officer for 8-years in the cities of Atlanta and LaGrange, Georgia. In Atlanta he served as a police patrolman. In LaGrange he served as a SWAT Team officer, superior court investigator, senior patrolman, school resource officer, and stakeout squad member. Duty related injuries and two major surgeries ended his career. He then became a tenured Criminal Justice Professor and Private Investigator in Washington State. As a college professor, he also served as an International Police Trainer, and as a Guardian ad Litem for at-risk children in Pierce County (Tacoma), Washington.

In 2002 Professor Gilbertson became a licensed private investigator and opened Gilbertson Investigations. He became a private investigator to maintain his state certification as a tenured professor in workforce education at Centralia College. He specialized in criminal defense casework for 12-years, completing over 100 pretrial investigations for defense attorneys. In 2014 he expanded his practice to Expert Witness casework. To date Professor Gilbertson has consulted on 80 criminal and civil rights cases in 17 states. He has testified in both state and federal courts as an expert witness.

In a recent U.S. District Court trial in Seattle – Moises E. Ponce Alvarez v. King County Sheriff’s Office, the presiding judge entered his opinion: “Mr. Gilbertson’s qualifications demonstrate extensive experience in policing. His experience includes work as a Georgia police officer, SWAT team officer, superior court investigator, school resource officer, stakeout squad officer, and senior patrolman.  After his law enforcement career, Mr. Gilbertson became a college professor and private investigator. He has taught courses in criminal justice and conducted pretrial investigations for attorneys in criminal cases. The Court finds his testimony can be expected to have a reliable basis in knowledge and experience.”

FEDERAL COURT: Professor Gilbertson has testified as an expert witness in U.S. District Court before Judges Thomas Zilly, Richard Jones, and Marsha Pechman. In 2018 he testified in the case of Josiah Hunter v. The City of Federal Way. This case involved a dangerous choke-hold employed by a Federal Way police officer against Mr. Hunter. The jury agreed with Professor Gilbertson’s analysis of excessive force and awarded Mr. Hunter $640,000.00 in damages.  Mr. Hunter’s attorney made the following statement after trial: We thank our expert, Professor Gregory Gilbertson, for his tremendous efforts on this case. His analysis is top notch.” James Bible, Attorney at Law, Bellevue, WA  

TESTIMONIALS: The following attorneys and clients have endorsed Professor Gilbertson:

“Professor Gilbertson has twice served as my expert in search and seizure and false arrest cases. His analysis and opinions are always spot on. I was impressed with his willingness to process a considerable amount of information. Methodical and thorough, he took the time to interview each client and determine the veracity of the information they provided. His work ethic is extraordinary, and his credentials are unassailable. I highly recommend him to other attorneys.”  Darryl Parker, Attorney at Law, Seattle, WA

I have been a personal injury lawyer for over 30 years. I have worked with many experts including Professor Gilbertson. He was our expert for an excessive force case in the U.S. District Court. He provided valuable input on the police on this matter, and on our cross examination of the respondent’s expert. He engaged with the jury and his testimony was solid. I recommend Professor Gilbertson as an expert witness in any case involving police misconduct.”  Patrick Trudell, Attorney at Law, Seattle, WA

Professor Gilbertson brought a high level of professionalism and competence to bear as an expert witness in a  murder trial. Once the prosecutor made demands for an expert opinion, he responded quickly and his conclusion were dis-positive. The  judge mentioned the credibility of his report in hearings. We considered his contribution to be highly effective in securing a dismissal for our client.”  Stephen Pidgeon, Attorney at Law, Everett, WA

“Professor Gilbertson was an expert in a criminal trial where self-defense was the primary issue. He was accessible, prompt, and thorough. He explained “use of force” and “self-defense” in a manner the jury easily understood. His testimony was an integral factor in achieving a not guilty verdict for our client at trial.” Michael Blanchard, Attorney at Law, New London, CT

“I reside in a gated community in Scottsdale. My family and I were victims of a violent, unlawful entry of our home by a SWAT Team. We were subjected to excessive force, false arrest, and defamation of character. Fortunately, I found Professor Gilbertson and contacted him. He was empathetic to my situation. I hired him to examine the facts of my case. I’m very pleased I did. His expertise uncovered legal findings that solidified my position of victimization. I strongly recommend Professor Gilbertson.” Nicholas Krakana, Scottsdale, AZ

CREDENTIALS: Professor Gilbertson’s expert witness credentials can be traced to his service as an International Police Trainer in Iraq and Afghanistan. In 2005-2006 the U.S. Department of Justice designated him a Subject Matter Expert in Police Practices and Procedures. He then deployed to Iraq and helped develop a Bachelor’s degree in democratic policing for the Baghdad Police College. He also served as Deputy Director of the Basrah Training Academy. In Basrah he supervised the training of 500 Iraqi National Police cadets by American, British, Czech, and Danish police trainers.

In 2008-2009 Professor Gilbertson served again as an International Police Trainer, this time for the U.S. Department of Defense in Kabul, Afghanistan. Upon arrival he produced a policy and procedures manual for the Afghan National Police. He then served as Senior Mentor and NATO Liaison to Lieutenant General Sayed Qudoosi, Commander of the Afghan National Police Academy. As the only American assigned to the police academy, Professor Gilbertson worked with Afghan, German, French, and Norwegian police officers in support of 2500 cadets and staff. He also secured 50 million dollars to upgrade academy curriculum, technology, and living conditions. In Baghdad, Basrah, and Kabul, Professor Gilbertson lived and worked for 2-years in active war zones. He was exposed to Al Qaeda and Taliban IED’s, small arms, rocket, and mortar fire nearly every day.

BACKGROUND: Professor Gilbertson enlisted in the U.S. Army in 1983 after graduating from the University of Washington with a Bachelor’s degree in History. He soon earned an appointment to the U.S. Army Officer Candidate School at Fort Benning. At graduation, 2nd Lieutenant Gilbertson was recognized as a Distinguished Military Graduate (top 10%) of O.C.S. Class 501-86. He attended Airborne School and served as a commissioned officer of infantry soldiers. In 5-years of military service, Lieutenant Gilbertson was decorated 4-times and received two General Officer letters of commendation.

Professor Gilbertson earned a Master’s degree in Justice Administration while serving as a police officer in Atlanta and LaGrange, Georgia. When duty related injuries and advanced Osteoarthritis made disabling surgeries inevitable, he left police work and began teaching criminal justice courses for Saint Martin’s University (Lacey, WA). He soon became a tenured professor at Centralia College. The curriculum he’s designed and developed was ranked by BestColleges.com in the “Top 10” of all 2-year criminal justice degrees in 2018.

In recent months Professor Gilbertson spearheaded a groundbreaking academic initiative for Washington State law enforcement officers called a “Crosswalk Degree.” The Crosswalk Degree aligned Washington State police academy and state patrol academy coursework with Centralia College curriculum. As a result of this initiative, Centralia College is the only academic institution in Washington State that confers 45 of 90 credits required to complete an Associate’s degree in Criminal Justice to police officers, deputy sheriffs, and state troopers for academy training and experience.
