Police Practices & Use of Force | Command, Policy & Training | Cold Case & Crime Scene Analysis
Professor Gregory Gilbertson (Ret.), FBI Special Agent Christopher Holland (Ret.), and Sheriff Robert Snaza consult with attorneys nationwide regarding police practices and procedures, use of force, false arrest, police misconduct, criminal, and self-defense casework.
The Hon. Richard A. Jones United States District Judge“Mr. Gilbertson’s qualifications demonstrate extensive experience in policing. His expansive work as a police officer in Georgia, with assignments as a SWAT team officer, juvenile court investigator, school resource officer, stakeout squad officer, senior patrolman, and patrolman; then a career as a tenured college professor and university lecturer teaching criminal justice courses to degree-seeking students at colleges and universities, and as a licensed private investigator conducting felony pretrial investigations for attorneys in Washington State in dozens of criminal cases, makes him unique in the field of police expert witnesses. The Court finds that, based on his experience, Mr. Gilbertson’s testimony can be expected to have a reliable basis in knowledge and experience of police practices.”
