A new Illinois law limits how police can use devices that cast a wide net in gathering cellphone data and are at the center of a lawsuit against the Chicago Police Department. Gov. Bruce Rauner signed the legislation into law on Friday and drew immediate praise from civil libertarians.
The technology, a cell site simulator, is perhaps best known by the brand name Stingray. It gathers phone-usage data on targets of criminal investigations, but it also gathers data on other cellphones — hundreds or even thousands of them — in the area.
The new law requires police to delete the phone information of anyone who wasn’t an investigation target within 24 hours. It also prohibits police from accessing data for use in an investigation not authorized by a judge.
