In contrast, full transparency of body cam footage could and would compromise ongoing investigations and identities of people in witness protection and so on. So full transparency in private/closed court or redacted versions showing only 'relevant' information in public/open court. Maybe full transparency after the information in the video becomes irrelevant, but micromanaging a hude amount of body cam footage would prove to be quite difficult.
