This was discussed a couple months ago here: https://news.ycombinator.com/item?id=19653647 https://news.ycombinator.com/item?id=19653647 My comment on it (expanded a little): Even without Google or Apple, the police have the cell service providers. In the case of the Austin bomber from a year ago[0], police got cell tower records from the multiple bombings and figured out who was at all the locations. Cell phones are little trackers unless you turn them off or don't carry one. The police don't need Google or Apple here, the carriers are already tracking who connects to what towers (and I believe they are required to do this by law) [0] https://www.google.com/amp/s/www.nbcnews.com/news/amp/ncna858791 https://www.google.com/amp/s/www.nbcnews.com/news/amp/ncna85...
