Law enforcement was able to track locations of protestors using social media sites before Facebook, Twitter, and Instagram cut them off.
The ACLU of California reported that Geofeedia had been providing law enforcement with data -- including locations -- from the social media accounts of protestors. In response, it said Tuesday that Twitter, Facebook, and Instagram had cut off Geofeedia's access to their feeds.
The extent of law enforcement's social media surveillance was discovered through public records requests of 63 agencies in California, according to the ACLU of California. Emailsobtained show the tools were used to monitor chatter around "the Ferguson situation," and that Geofeedia told California law enforcement agencies to find out how police in Baltimore used its tools to "stay one step ahead of rioters," after the death of Freddie Gray in police custody.
Geofeedia provided searchable data from public Instagram posts, troves of publicly shared information from Facebook (FB, Tech30) via the Topic Feed API, and public tweets. Information in Twitter, Facebook, and Instagram posts can be used to infer things like location, personal associations and religious affiliation.
