Police Minister Mark Mitchell says told Mike Hosking that police bodycams would help clear up misconceptions in the field.

He says he was talking to a young constable who was coward punched and a body camera would've made for compelling evidence.

Police Commissioner Richard Chambers wants the cameras to be implemented after a decision was put off last year. 

Police are still looking into ways to deal with transparency issues laid bare when new tasers for frontline officers didn't include a camera.
