The City Council has passed legislation forcing the NYPD to explain how it uses facial recognition and other surveillance technologies to track New Yorkers.

The Public Oversight of Surveillance Technology Act was first introduced in March 2017 and had picked up 38 council sponsors ahead of today’s vote. If signed by Mayor Bill de Blasio, the measure would require the NYPD to report and evaluate its surveillance technologies and would compel the department to create a “surveillance impact and use policy.”
