I'd like to know where companies like https://www.hawkanalytics.com/cellhawk/ https://www.hawkanalytics.com/cellhawk/ and https://en.wikipedia.org/wiki/Fog_Reveal https://en.wikipedia.org/wiki/Fog_Reveal get location data on US citizens legally without the permission of those citizens, and how them buying such info isn't illegal surveillance, and how reselling the data to law enforcement is not selling stolen property for them, and receiving stolen property for the fuzz (assuming, maybe wrongly so, that I own my location data as PII)
