Mass deployment on public property and the network effect that having them all connected and using things like license plate readers is all pretty new.
Largely the US hasn’t had widespread surveillance, it’s been private property ownership of CCTV type systems for security reasons which Americans are ok with. Reading my license plate, face, gait, etc every 100 meters as I move across a large distance loses the security reason and entered the world of mass surveillance. Which while many of us struggle with caring about, is seen as infringing on our right to privacy which itself has a complex legal interpretation of and where systems like this cross a line into what is acceptable. The fact that law enforcement can query flock to learn of an individual’s location without any warrant is often seen as directly opposing a constitutional protection from government search. It might also be important to know that the US Constitution is seen as a law of physics in some areas and that most laymen that read the Fourth Amendment would come to the conclusion that this is not allowed and thus unconstitutional at its core. There’s of course legal things that have happened since that clarify interpretation of the constitution so the wiggle room they have to operate, especially when it’s something the government wants to exists, is enough for now. The Supreme Court would be the ones to eliminate grey area. They recently issued a ruling taking a heavier privacy stance. Meanwhile, people on the street have grown deep distrust in tech and government which is visible as they are destroying these cameras.
