You're focused on the narrowness of the final ruling and not the vast legal reasoning that led to it.

Carpenter's reasoning concerning comprehensive records of an individual's movements (regardless of private or public) are relevant when LE uses aggregated Flock data to reconstruct a person's movements over an extended period.

Except the narrowness of the final ruling is exactly what makes it not impact the legality of Flock. It doesn't matter whether you think the courts decision should be extended to cameras - your opinion doesn't decide the law, the court's opinion does.
