Preferably, but even in areas where police fight tooth and nail to keep them we can fix the problem. Granted the fix will probably result in them being removed.
The fix is a couple parts:
1) Requiring a warrant issued by a state judge to access the cameras at all, with the requirement that the officer personally testify to facts. No fobbing it on random informant, they are required to own it.
2) Accessing the cameras without a warrant is a felony worth a minimum of 5 years in prison, but up to 10 years.
3) Regular transparency conducted by an independent group, not associated with the police.
4) Since we're dealing with cameras make it a felony worth 10 years in prison to hamper, mute, disable, modify, or otherwise obstruct, the operation of a body / dash camera during an interaction or when discussing an interaction. No blocking the camera, mic, or secret conversations with your coworkers.
Of course the ideal solution will be to keep pushing for these things to be shoved off into oblivion.
As a side note, if they try to claim that a warrant is too high a burden because "it needs to happen fast" or whatever false emergency situation they dream up, then ask them again if the cameras are active surveillance. They have to say no. Then you can remind them that it's not hot pursuit or anything similar since they're looking at historical, not real-time, data so they should be able to take a few minutes to get a judge to issue a warrant over the phone.
