I understand the vast majority of CCTV is private-sector. That doesn't matter when it is handed over to the government with little to no push back when the government asks for the footage.

When you'd only need CCTV to confirm with facial recognition that your suspect was in the area you wouldn't need CCTV coordination - that would be the entire point of deploying a WALDO network. It lowers the number of CCTV you'd need to coordinate with to track someone's movements.
