Evidence Hub

Law Enforcement Brazilian Jiu-Jitsu Evidence Hub

This central repository hosts case reports, training standards, and curricula guidelines relating to physical control, grappling, and jiu-jitsu training programs for policing agencies.

What the Evidence Supports

  • Controlled Resistance Practice: Gives officers recurring opportunities to practice physical techniques against active, non-compliant partners in a safe training environment.
  • Positional-Control & Balance: Develops skeletal framing, weight distribution, and leverage control to hold or move a subject without relying on strikes or blunt force.
  • Pressure Decision-Making: Improves physiological control and composure, helping officers slow down and make decisions under physical stress.
  • Operational Testing: Suggests potential benefits in safety and injury reduction that are worth testing through a supervised department pilot.

What the Evidence Does Not Establish

  • Guaranteed Reductions: Marietta's reports are department-reported data and do not guarantee equivalent statistical outcomes for another agency.
  • Automatic Compliance: Training alone does not guarantee policy adherence; tactical training is supplemental to department directives.
  • Sport BJJ Generalization: Standard sport BJJ techniques require specific adjustments for duty belts, weapons retention, and multiple subjects.
  • DT Replacement: BJJ is supplemental and does not replace official, department-approved defensive-tactics instruction or state training requirements.
