So I’ve just been thinking about privacy, and how everyone’s location can be tracked. Then I realized: What about people who have no permission to enter the country?
Like do they just decide to not have a phone, or do they still have phones and just roll the dice and hope they don’t get caught?
That makes it wholly unsuitable for a dragnet surveillance system.
Further, a business can aquire data that a police agency can’t gather without a warrant.
