Lawyer sues Chicago police, claims they used stingray on him

A local attorney has sued the City of Chicago and numerous police officials in a proposed federal class-action lawsuit, claiming that he and countless others were unconstitutionally searched when the police used a cell-site simulator without a warrant. In the suit, Jerry Boyle, who describes himself as an “attorney and longtime volunteer legal observer with the National Lawyers’ Guild,” alleged that while attending the “Reclaim MLK Day” event in Chicago nearly two years ago, his phone was targeted by the Chicago Police Department’s device, better known as a stingray. Boyle argued that his Fourth Amendment and First Amendment rights were violated as a result.

Stingrays are used by law enforcement to determine a mobile phone's location by spoofing a cell tower. In some cases, stingrays can intercept calls and text messages. Once deployed, the devices intercept data from a target phone along with information from other phones within the vicinity. At times, police have falsely claimed the use of a confidential informant when they have actually deployed these particularly sweeping and intrusive surveillance tools. Often, they are used to locate criminal suspects.
