This would still be an issue even if they weren't recorded in private spaces. At issue here is the reconstruction of data, regardless of if it happened in public or private spaces.
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.
Only when that tracking is done via cell phone location information. The Carpenter decision did not apply this to all forms of public monitoring. You keep ignoring the fact that the decision was narrowly scoped to cell phone location data, and continue to erroneously claim that it applied to public tracking in general.
