"May"? This is exactly how the January 6th protestors were identified.

doubtful. they were issuing subpoenas to the cell companies for their records of the tower registrations for a certain time frame when crimes were being committed. It doesn't take much to identify the owner of a smartphone via that and then correlate that with driver's license photo ids and correlate that with surveillance camera footage to bring a case. that had nothing to do with peaceful protester tracking but bog standard criminal investigation.

I posted the source in another comment but I'll put it here as well: https://www.businessinsider.com/doj-is-mapping-cell-phone-lo...

The data came from Google and included GPS data.

Either way, I don't think that matters. My point is that tech companies store data that can be used to identify everyone present at a specific location and timeframe, and that data is easily available to the government. There's no "may" about it.
