All Police Video (body cams and vehicles) should be uploaded to a Public Database or Watch Group, Police should have no control over what they record. This will help with accountability and we will no longer have to take their word for it, also it will probably help with all the footage that magically disappears or is edited to fit the police agenda. If they are truly public servants then we should have the right to view what they do.
Propose a law that requires all video of police activities to be recorded, maintained, handled etc exclusively by a disinterested 3rd party. I would even pay a new tax to make this happen.
