Talk about making bogus excuses.  Hard drive memory storage is cheap.  Anyone who has security camera system will store up to a month or so of video from many cameras and when the hard drives(s) run out of space it overwrites the earliest video.  If the body camera video is routine why would you need to store it forever?  If something notable is captured on the body camera, you would immediately copy it separately and save it permanently.   All routine body camera videos should be stored up to a month and then overwritten with incoming new videos.  It wont work if the cop has the ability to turn off his camera.  Like on the mainland when a cop shot an unarmed woman from the police cruiser, the cops turned off their body camera before they arrived onto the scene.  If the cop could not have turned off his camera, it would have probably shown a panicked cop that shot first and asked questions later when the woman pounded on the car with her hands before going up to talk with the cops.
