The San Francisco Police Department (SFPD) conducted mass surveillance of protesters at the end of May and in early June using a downtown business district’s camera network, according to new records obtained by EFF. The records show that SFPD received real-time live access to hundreds of cameras as well as a “data dump” of camera footage amid the ongoing demonstrations against police violence.
The camera network is operated by the Union Square Business Improvement District (BID), a special taxation district created by the City and County of San Francisco, but operated by a private non-profit organization.
