Jeffrey J. Noble: Police Practices Expert Witness and Attorney

Jeffrey J. Noble is a retired law enforcement executive, licensed California attorney, and police practices expert who has been retained in more than 300 civil, criminal, and arbitration cases across 26 states. A former deputy chief of the Irvine, California, Police Department, he now runs an independent consulting firm and has testified or consulted in some of the most prominent police-conduct cases of the past decade, including the deaths of Tamir Rice and Philando Castile.¹

From Patrol Officer to Deputy Chief

Noble joined the Irvine Police Department in 1984 and served for 28 years, retiring in July 2012. He worked as a patrol officer, narcotics detective, traffic detective, training sergeant, SWAT sergeant and commander, internal affairs sergeant, lieutenant, and area patrol commander before being appointed deputy chief in 2010. At his retirement, Irvine Police Chief Dave Maggard called him an “exceptional police manager” and a “highly regarded leader.”²

Legal and Academic Credentials

Noble holds a bachelor’s degree in criminal justice from California State University, Long Beach, and a Juris Doctor from Western State University College of Law, where he graduated with honors in 1993 and served as assistant editor of the Consumer Law Journal. He was admitted to the California State Bar in 1994. He is also a graduate of the Senior Management Institute for Police at Boston University, a program run by the Police Executive Research Forum.³

Consulting Firm and Client Base

After leaving Irvine, Noble founded Noble Consulting and Expert Witness Services, LLC. The firm handles independent police practices inquiries, department audits, policy reviews, and expert witness analysis, and has worked with major cities including San Francisco, Los Angeles, Chicago, Seattle, Austin, Denver, and Miami.¹ His declared areas of expertise span use of force, police misconduct, pursuits, interrogations, investigations, Monell municipal liability claims, and alleged wrongful convictions.⁴ Noble accepts retention from both plaintiff and defense counsel, an unusual posture for a police-practices expert.

High-Profile Expert Witness Work

Tamir Rice

In 2015, the family of Tamir Rice, the 12-year-old shot and killed by Cleveland Police Officer Timothy Loehmann, retained Noble. His expert report concluded that the officers “engaged in reckless tactical decision making” that directly created the danger leading to the boy’s death, faulting them for driving onto the grass directly to the gazebo rather than stopping at a distance to survey the scene, wait for backup, and use cover.⁵ Noble wrote that Loehmann’s use of deadly force was “excessive, objectively unreasonable, and inconsistent with generally accepted police practices,” noting the shooting occurred within 1.7 seconds of Loehmann exiting the patrol car.⁶

He also criticized the officers’ failure to provide basic first aid and questioned Loehmann’s hiring, pointing to a prior personnel file from the Independence Police Department that described him as “immature and incompetent” and cited “acts of dishonesty.”⁷ Noble challenged experts retained by prosecutor Timothy McGinty, arguing that under Graham v. Connor and Sixth Circuit precedent a jury can assess whether an officer’s reckless tactics contributed to the need for lethal force.⁶

Philando Castile

Noble served as a prosecution expert in the 2017 manslaughter trial of Officer Jeronimo Yanez, who fatally shot Philando Castile during a traffic stop in Falcon Heights, Minnesota. Testifying in person, he told the jury that Yanez’s decision to use deadly force was “objectively unreasonable” and that there was “absolutely no reason” to believe Castile was the suspect in an armed robbery, stating that Castile “was simply a black man who drove by the convenience store four days later.”⁸

Noble testified that Yanez had tactical alternatives, including moving to the B-pillar of the car to create distance and time, and that a reasonable officer would have instructed Castile to put his hands on the steering wheel. He cited a recorded conversation in which Yanez told a supervisor, “I don’t know where the gun was,” as evidence the officer had not actually seen a firearm before firing.⁸

Ryan Londregan and Ricky Cobb II

In 2023, the Hennepin County Attorney’s Office hired Noble to consult on the fatal shooting of Ricky Cobb II by Minnesota State Trooper Ryan Londregan. A two-page memo summarizing an October 2023 meeting recorded that Noble initially observed a “reasonable officer” might have acted similarly to protect a partner being dragged by a vehicle, but he “refrained from offering an ultimate opinion” and asked for more time to review the case materials.⁹

Defense attorneys later alleged that Noble had told prosecutors Londregan “committed no crime.” The Hennepin County Attorney’s Office responded that the defense was selectively quoting a preliminary meeting and that Noble had not reached a legal conclusion.¹⁰ County Attorney Mary Moriarty stopped working with Noble and charged Londregan with second-degree murder, manslaughter, and first-degree assault without an expert, saying her office was “able to determine charges were appropriate” on its own.⁹

Chicago Litigation

Noble has been retained in cases involving the Chicago Police Department, including Hobley v. Burge, which alleged confessions coerced through torture, and Estate of Pierre Loury v. City of Chicago, a Monell liability case. In Loury, a federal judge partially excluded some of his defense-side opinions, including his assertions that there was “no evidence” of systemic disciplinary failure or a code of silence, finding they invaded the jury’s province and weighed evidence rather than offering expert analysis. Other opinions were barred for failing to explain his methodology. The court reserved ruling on several additional opinions and did not exclude him as an expert entirely.¹¹

Books and Published Writing

Noble has co-authored two books that are widely cited in the field. Managing Accountability Systems for Police Conduct: Internal Affairs and External Oversight (Waveland Press, 2008), co-written with University of South Carolina criminologist Geoffrey P. Alpert, addresses internal investigations and civilian oversight.³ Evaluating Police Uses of Force (NYU Press, 2020), co-authored with Seth W. Stoughton and Alpert, examines use-of-force incidents through four lenses: constitutional law, state law, administrative regulation, and community expectations. Barry Friedman of NYU School of Law called it “the most comprehensive treatment of police use of force there is,” and National Review described it as “an excellent reference for lawmakers and reformers.”¹²

Noble and Alpert also wrote “Criminal Interrogations of Police Officers After Use-of-Force Incidents” for the FBI Law Enforcement Bulletin in September 2013. The article argued against automatic “cooling off” periods before officers are interviewed, contending such delays can harm transparency and the accuracy of officer statements, and advocated cognitive interviewing techniques using open-ended questions and narrative responses. The authors wrote that “the manner in which an agency investigates its own, especially after a shooting incident, directly impacts the public trust.”¹³ His other articles have appeared in Police Quarterly, Police Chief Magazine, The Tactical Edge, The Journal of California Law Enforcement, and The Atlantic, covering officer truthfulness, Brady disclosure obligations, tactical decision-making for warrant service, and the evaluation of investigative quality.³

Professional Affiliations

Noble is a member of the California Peace Officers’ Association, where he chairs the Communications Sub-Committee, as well as the Police Executive Research Forum, the International Association of Chiefs of Police, and the National Tactical Officers’ Association. He has served as a peer reviewer for the National Institute of Justice and the Office of Community Oriented Policing Services, and he chaired the Major Cities Chiefs of Police Task Force on Internal Affairs from 2005 to 2008.³
