Deputies may mute the audio function of the BWC system when they are not interacting with a suspect, witness, victim, or other person involved in an incident. When it is necessary to mute the audio, deputies should verbally state the reason before muting or immediately upon unmuting. If the video is stopped for taking evidentiary photographs, change of assignment (SWAT, MOURT, etc…), personal break, or other justified reason the deputy should narrate into the BWC the reason for stoppage and if needed when video is restarted.
