In New York state court, EFF and the Brennan Center for Justice at New York University School of Law joined an amicus brief written by the New York Civil Liberties Union (NYCLU) that provides a stark visualization of why police should get a warrant to obtain cell site information. Police obtained more than six months of cell site information—more than 10,000 data points—on Ali Moalawi without a warrant. This data painted a vivid portrait of when and where he went, including when he was at home or spent the night somewhere else. The NYCLU visualized these trips on a map, showing Moalawi’s cell site connection records on March 1, 2014, when Moalawi appeared to spend the morning at home before heading to the Bronx and then finally Brooklyn where he stayed until late in the evening.
