My guess is the vast majority of the 80,000 or whatever cameras are uncontested politically. Local board meetings for most towns are boring and quiet affairs, and those are also the most effective venue for these concerns.

If you are a taxpayer in a local jurisdiction with Flock cameras and you want them removed, show up to every single meeting and maximize use of public comment time.

Local government is a place individuals can actually be extremely effective but also almost nobody ever actually does.
