Today, New America’s Open Technology Institute (OTI), Color Of Change, and Center for Media Justice filed a complaint at the Federal Communications Commission (FCC) against the Baltimore City Police Department (BPD) for its extensive and racially-biased use of fake cellular towers known as “cell site simulators” (“CS simulators,” sometimes called “Stingrays”), which it uses to locate and track cellphones. The complaint alleges that BPD’s use of these devices violates the Communications Act....BPD’s use of these devices interferes with the cellular network, including with emergency calling services. Worse, these harms fall disproportionately on Black neighborhoods where BPD disproportionately exercises its enforcement authority in a racially biased way.
