When an officer deploys a TASER, some information is forensically stored on the device, but some information is not. For example, whether or not the discharge was a hit, a miss, or a partial discharge, has not — until now — been easily identifiable. Officer Chris Myers of the Seattle Police Department explains how one of the forensics experts with the Washington State Patrol Crime Laboratory has devised a new way to determine the approximate length of a TASER discharge by looking at the TASER probe itself.
