While law enforcement sometimes argues that making members of the public aware that cell phone companies can track them will make it more difficult to catch criminals, it is too late in the day for that argument now that cell phone tracking is a staple of television police procedurals… Why aren’t these policies available on the companies’ websites? With such information, consumers could vote with their wallets and punish those companies that don’t protect privacy. Keeping their customers in the dark about surveillance is better for business, it seems.
