Be careful of what you wish for. My son had been wearing one for months now on Maui. Initially grumbled,  but actually likes it .
Patrol is now gathering all kinds of intelligence for support plainclothes units like vice,  CID,  CRU. Cops Go to a domestic at a drug House , camera is videoing scene,  people present. Cops making traffic stops, amazing on who is hanging around who all on càmera, fills spaces on an link analysis chart. DUI stops, all the behavior ques, slurred speech, failing yo follow instructions... the Big one, " spontaneous utterence". Another one, at the end of shift when they down load data, they share what they csptured.... sometimes people think they cute give a fake name on an encounter.... one officer might know who that person actually is, sees person on recording to include "wants". They climb back in their patrol car, find person and arrest.... cha-ching OT,  camera paid for itself. Watch gets an arrest stat, Sergeant is Happy
