> Do you believe Flock cameras have been rolled out en masse across the entire country all at once because there is near-unanimous democratic support for their presence?

I'm not sure where you got "near-unanimous" from. I think Flock cameras were rolled out en masse because public video surveillance has been common for a long time, and polling data has historically suggested (e.g. https://yougov.com/en-us/articles/5881-63-accept-video-surve...) that Americans are fine with it.
