Wired reports of U.S. law enforcement using artificial intelligence software to monitor social media is sparking privacy concerns.

Zencity redacts personal information from the reports and does not allow its users to see individuals' profiles. The surveillance tactic remains controversial, with Pittsburgh City Councilor Deb Gross noting, "Surveilling the public isn’t engaging the public. It's the opposite."
