The way these surveillance systems work, a better analogy is one where everyone has a police officer following them around. And, if that were to happen today, you could take that police officer to court for harassment/stalking. Similarly, were the police to attach a GPS tracker to you or your vehicle without a warrant, there's already legal precedent that it's a Fourth Amendment violation.

You have to look at this from a systems point of view. Yes, flock cameras individually only capture their immediate surroundings, but the emergent behavior of the system is a means to follow someone around wherever they go, which is already a no-no in our legal system without at least securing a warrant to do so. And, even securing a warrant for one individual does not give you the right to include everyone in an area, commonly referred to and struck down as dragnet surveillance.

Flock systems and their siblings are wrong and should not be tolerated.
