CASEWORK: Professor Gregory Gilbertson and his colleagues have consulted with civil rights and criminal defense attorneys in 14 states on nearly 70 cases. They have provided analysis and opinions on incidents involving excessive force, police misconduct, false arrest, high-speed pursuits, and self-defense. In a recent U.S. District Court civil rights trial – Moises E. Ponce Alvarez v. King County Sheriff’s Office, the presiding judge for the Western District of Washington entered the following ruling to King County’s motion to exclude Professor Gilbertson’s testimony:

“Mr. Gilbertson’s qualifications demonstrate extensive experience in policing. Mr. Gilbertson’s experience includes work as a police officer in Georgia, including assignments as a SWAT team officer, superior court investigator, school resource officer, stakeout squad officer, senior patrolman, and patrolman. After his law enforcement career, Mr. Gilbertson went on to become a college professor—where he taught courses in criminal justice — and a private investigator conducting pretrial investigations for attorneys in hundreds of criminal cases. The Court finds that, based on his experience, Mr. Gilbertson’s testimony can be expected to have a reliable basis in the knowledge and experience of police practices.”

U.S. DISTRICT COURT: To date, Professor Gregory Gilbertson has testified as an expert witness in the U.S. District Court for the Western District of Washington before Judge Thomas Zilly, Judge Richard Jones, and Judge Marsha Pechman.

In July 2018 Professor Gilbertson testified as a Use of Force expert for plaintiff’s attorney James Bible in the case of Josiah Hunter v. The City of Federal Way Police Department. This case involved a claim use of excessive force by Mr. Hunter against a Federal Way police officer that used a Lateral Vascular Neck Restraint to arrest him in September 2014 for misdemeanors that were later dismissed by city prosecutors.

The U.S. District Court entered a judgment against the arresting officer and Federal Way Police Department for excessive force totaling $640,000.00 in actual and punitive damages.  Mr. Bible made the following statement after the trial: “We would like to thank our expert, Professor Gregory Gilbertson, for his tremendous efforts on this case. He presents well in front of a jury and his analysis is top notch.” 

CLIENT TESTIMONIALS: The following clients endorse Professor Gilbertson as an expert witness in civil rights and criminal defense casework:

“Professor Greg Gilbertson has twice served as my retained expert in search and seizure and false arrest cases. His analysis and opinions were always spot on. I was most impressed with his willingness to take on and process a considerable amount of information. Methodical and thorough, he took the time to interview each client and determine for himself the veracity of the information they provided. His work ethic is extraordinary, and his credentials are unassailable. I would not hesitate to work with him again and highly recommend him to other attorneys.” Darryl Parker, Attorney at Law, Seattle, WA

I am a personal injury trial lawyer who has been trying cases in King and Snohomish Counties for over 30 years. I have worked with many experts including Police Misconduct Expert Professor Gregory Gilbertson. Professor Gilbertson was our expert witness in 2017 for a 42 U.S.C. 1983 case at the United States Federal District Court for the Western District of Washington. This case proceeded to a jury trial.

My co-counsel and I met with Professor Gilbertson at a local college. Professor Gilbertson was prepared for our meeting. He listened to our input on the facts of the case, took time to insure his understanding was accurate, and provided input on the police conduct in our case.  He also provided us with guidance on his direct examination, and on our cross examination of the respondent’s expert witness. We were never rushed and were able to bond with him as our expert. He left us knowing he was available for other pre-trial work.

Professor Gilbertson arrived early for his trial testimony. His direct examination went well. He engaged with the jury, his testimony was solid, and he was did not over advocate. On cross examination Professor Gilbertson was consistent in his testimony and his demeanor. He was a solid expert witness who testified with credibility. I recommend Professor Gilbertson as an expert witness in any case involving police misconduct and practice issues. We look forward to working with Professor Gilbertson in the future.” Patrick Trudell, Attorney at Law, Seattle, WA

Professor Gilbertson has again brought a high level of professionalism and competence to bear as an expert witness in our most difficult murder trial. Once the opposition made demands for a rushed expert witness opinion, Professor Gilbertson not only responded quickly, but eloquently, and his language and conclusion were dis-positive, the trial judge mentioning its credibility in hearings. We considered Professor Gilbertson’s contribution to be highly effective, and we intend to use him again when the necessity arises.” Dr. Stephen Pidgeon, Ph.D., Attorney at Law, Everett, WA

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

“I reside in a gated community in Scottsdale, Arizona. My family and I were victims of a violent, warrantless entry of our home, based upon false pretenses, by the Scottsdale Police Department SWAT Team. We were subjected to excessive force, false arrest, and defamation of character by these officers. Fortunately, I found Professor Gilbertson online, read his credentials, and contacted him. Professor Gilbertson was receptive and empathetic to my situation. I hired him to examine the facts and circumstances of my case. I am very pleased I did. His expertise and insight uncovered legal findings that solidified my position of victimization by the Scottsdale Police Department. He genuinely cares, and worked diligently on my case. I recommend Professor Gilbertson to anyone in need of his expertise.” Nicholas Krakana, Scottsdale, AZ
