It sounds to me like intrinsic concerns aside, the original process for acquiring footage seemed reasonable. It’s not really any different from if the police asked for CCTV records from a local business or similar. A huge problem was the creation of a streamlined request portal where cops could just ask for whatever they wanted, with little oversight. I’m increasingly curious what a model for a society where voluntary compliance with production of business records wasn’t acceptable, and any request for records had to come with a real warrant, signed by a real judge.
