As a principled opponent of Panopticon tracking cameras and an unprincipled opponent of speed cameras, I would put them in radically different categories.
Speed cameras and red light cameras only take a picture when they detect a violation in a particular location. If you don't want your picture taken, don't speed or don't run the light.
Flocks and their ilk take pictures of everyone and track everyone everywhere, with the data being stored in completely unaccountable private clearing houses available for purchase by more or less anybody with enough money, and ripe for abuse. It's already been well documented that while cops are required to provide a reason for searches, they can just enter "chicken" and it's good enough.
If I parked across the street from Flock's Atlanta headquarters and took pictures of every car coming and going, followed them around town, found out where they live, where their kids go to school, where they go to church, staying entirely in public, I'd be rightfully considered a creep and probably arrested. If machines do it in the name of Safety and Security, it's fine.
