The San Jose PD regularly conducts warrantless searches through its massive license plate reader database, allowing it to reconstruct detailed maps of a person’s movements through the City going back as far as a year. This poses a serious threat to communities’ privacy and freedom of movement.

If ICE agents on *our public streets* aren't exempt from drunk driving laws, why should ICE agents on *our public streets* be exempt from laws banning masked government agents?
