FB, Twitter block app police used to monitor protests

Facebook, Instagram, and Twitter have blocked location-data analytics platform Geofeedia from access to their data after it was revealed that some law enforcement agencies were tracking activists and protesters via the platform, according to the American Civil Liberties Union (ACLU) of Northern California.

Geofeedia collects real-time, publicly available, social media data based on geographic locations. And although the company openly markets this data to a range of public and private businesses, including 500 law enforcement and public safety agencies, the issue for Facebook, Instagram, and Twitter arose after the ACLU noted conflicts between the three social media companies’ privacy policies and the sharing of user data.

“Because Geofeedia obtained this access to Twitter, Facebook and Instagram as a developer, it could access a flow of data that would otherwise require an individual to ‘scrape’ user data off of the services in an automated fashion that is prohibited by the terms of service,” ACLU public attorney Matt Cagle said in a blog post. “With this special access, Geofeedia could quickly access public user content and make it available to the 500 law enforcement and public safety clients claimed by the company.”

In addition to analyzing the public stream of user posts on Instagram using the developer API, Geofeedia signed a deal with Facebook to access the Topic Feed API on the social network. Access to the Topic Feed API allowed the company to gain a ranked feed of public Facebook posts that mention topics, hashtags, events or specific locations.

Twitter did not provide full access to its “firehose” of tweets and user data, but gave Geofeedia access to a searchable database of public tweets.

Facebook terminated Geofeedia’s access to its network in September.

Twitter attempted to modify its contract with the company to no avail, eventually sending them a cease and desist letter. After Cagle’s blog post was published on the ACLU website, Twitter announced it had terminated the company’s access to its database.

Some police departments have shelled out tens of thousands of dollars in contracts with Geofeedia, which is also used by journalists and retailers.

The Baltimore County Police Department described its use of the software in a “case study” obtained by the ACLU. Police used the service when riots broke out in Baltimore in April 2015 following the death of a black man, Freddie Gray, while in police custody.  “In some cases, police officers were even able to run social media photos through facial recognition technology to discover rioters with outstanding warrants and arrest them directly from the crowd,” the Geofeedia case study said.

Baltimore County police spokeswoman Elise Armacost praised Geofeedia as a “valuable law enforcement tool,” and said in an email to NBC News that it can be used during cases of school threats and criminal investigations.

“There is no difference between a detective who reads someone’s open source [public] tweets and a detective who hears someone say something on an incident scene,” Armacost said. “Law enforcement has an obligation to use available tools to gather information critical to public safety.”

She added that the Baltimore County Police Department is assessing whether to continue its contract with Geofeedia given the clamp down by social media platforms.

T.J. Smith, a spokesman for the Baltimore city police, said his department will also review its contract with Geofeedia and evaluate whether it remains effective. The city has an $18,000 a year contract, The Baltimore Sun reported.

A Facebook spokesperson told CNNMoney that Geofeedia only had access to data that people chose to make public and was subject to the company’s usage policies.

Facebook’s policy states companies can’t sell, license, or purchase Facebook data, transfer it, or funnel it into a search engine or directory, though it does not mention surveillance.

Geofeedia did not respond to request for comment on how its software might have been used to target protestors other than to provide a statement from CEO Phil Harris.

“Geofeedia has in place clear policies and guidelines to prevent the inappropriate use of our software,” the statement read. “These include protections related to free speech and ensuring that end-users do not seek to inappropriately identify individuals based on race, ethnicity, religious, sexual orientation or political beliefs, among other factors.”

In the statement, Harris also said, “Geofeedia will continue to engage with key civil liberty stakeholders, including the ACLU, and the law enforcement community to make sure that we do everything in our power to support the security of the American people and the protection of personal freedoms,” the company said.

Do you agree with either or both of these assertions? Explain your answer.

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. (from CNN Money)
