Good thing the courts are already upholding the constitutionality of Flock in US v Jackson and Schmidt v. City of Norfolk. If it reaches the SC, I think it'd be easy to see a limit similar to Carpenter on scope and duration of the searches of the database without a warrant, but recognize fundamentally that collecting the data itself is not violating anyone's rights.

As just mentioned, being watched in a public space doesn't constitute a violation of the 4th Amendment. Under any rational reading, you are not being searched.

It really has no impact on anyone's life, especially if they participate in any part of society. Your phone records, credit cards, and every social media and email account are all far more invasive tracking and without even the veneer of accountability. Even for criminals, it hardly makes a difference if they pull an ID from Flock, your cell records, or the bodega security camera and Ring doorbell footage people would happily offer to a cop. Investigating a crime by looking at a security camera is not fascism, just like deporting an illegal immigrant or dispersing a riot isn't fascism.
