99% of the population is voluntarily carrying sophisticated tracking devices with self-reporting always on
even if the signal is off it catches up later
with SEVERAL layers of tracking
not just your phone carrier but Google+Apple stores have your location as the apps are always on in the background
even phone makers have their own tracking layer sometimes
we know EVERY person that went to Epstein Island from their phone tracking and they didn't even have smartphones back then
Flock is just another lazy layer/databroker
Judges require warrants to put a GPS tracker on your car. Now that Flock cameras are so ubiquitous in many cities, this gives them access to the same data without a warrant.
