Activists use tech to fuel their movements, and cops turn to Geofeedia to aggregate the data

A burst of fire from an automatic rifle rings out on a deserted city street, and, instantaneously, a gunshot detector working in conjunction with a smart surveillance camera identifies the location of the shooting. The system automatically alerts a social media monitoring website, which establishes a digital, geo-location perimeter on a map of the neighborhood.

Now, any posts on Facebook, Twitter, Instagram, or any other location-tagged social media uploaded in that area will appear on a display at police headquarters. An uploaded Vine from one block away could show someone running away, and give the cops a starting point for their investigation.
