"GPS Bullets" Allow Police to Shoot a Tracker Onto a Car

"GPS Bullets" Allow Police to Shoot a Tracker Onto a Car

Wednesday we learned that the NSA is collecting location information en masse. As we’ve long said, location data is an extremely powerful set of information about people. To flesh out why that is true, here is the kind of future memo that we fear may someday soon be uncovered:

Dear commissioner: now that we have finalized our systems for the acquisition and processing of Americans’ location data (using data from cell phone and license plate readers as well as other sources), I wanted to give you a quick taste of our new system’s capabilities in the domestic policing context.

As you can see in this screen shot from our new application, an individual by the name of Jack R. Benjamin yesterday was flagged as a potential DUI risk:
