“It’s not just the National Security Agency secretly vacuuming up your personal data. Local police agencies are increasingly adopting Big Data technologies such as automatic license-plate readers that gather information about everyone, whether they’ve broken the law or not. A lot of the information ends up on the 14th floor of a federal office building in San Francisco, where a ‘fusion center’ run by state and local law enforcement agencies combines the data with a plethora of personal information about you, from credit reports to car rentals to unlisted phone numbers to gun licenses.”
