Marietta Police BJJ Study & Control Research
This reference page details the empirical findings from the Marietta, Georgia Police Department's mandatory Brazilian Jiu-Jitsu initiative and its impact on officer safety, suspect safety, and de-escalation efficiency.
Key Statistical Findings from the Marietta Initiative
In 2019, under Chief Dan Flynn, the Marietta Police Department implemented a mandatory weekly Brazilian Jiu-Jitsu training program for all newly hired officers. The agency tracked injury metrics, use-of-force events, workers' compensation claims, and citizen complaints compared to officers without BJJ training:
- 48% Reduction in Officer Injuries: Officers trained in BJJ sustained nearly half as many injuries during arrests compared to non-trained personnel.
- 53% Reduction in Suspect Injuries: Leverage and position control allowed officers to control subjects without striking or resorting to high-impact force.
- 59% Reduction in Overall Use of Force Incidents: Confidence in close-quarters grappling reduced panic responses and allowed officers to maintain composure under stress.
- $66,700 Estimated Annual Workers' Comp Savings: Significant reduction in medical claims and lost work shifts.
Why Leverage & Control Outperform Striking
Traditional law enforcement defensive tactics often relied on static compliance holds or striking. However, in high-adrenaline confrontations, panic and lack of position control frequently led to escalation.
Brazilian Jiu-Jitsu provides officers with a non-lethal, non-striking control framework. By understanding distance management, base, and joint manipulation, officers can safely pin and handcuff a resisting individual while keeping both the officer and the subject safe from traumatic injury.
