Subject dropped by M26 safely. • “The attending ER physician removed the probes and commented on how little damage was done in comparison to the damage he usually saw after a subject was involved in a physical confrontation with officers. Probes and self-inflicted slash to left wrist and no injuries to officers.” Comparison of Injuries TASER Technology Reduces Injuries 80% 78% 78% 80% 70% 60% Suspect Injured 60% 50% 45% 36% 40% 29% 30% 20% 16% 18% 11% 10% Chemical Spray Swarm Kick Baton Punch Flashlight 0% Misc. body force 5% 0% 0% Officer Injured / Affected TASER 20% 21% 29% Force Type Source: Study of Use of Force at Los Angeles Police Department, Greg Meyer.
