SPRINGFIELD, Ill. (AP) — Gov. Bruce Rauner has signed a law limiting police use of devices that can collect cellphone data and track phone locations.
The Republican took action Friday on technology — often known by the brand name Stingray — that gathers phone usage data on targets of criminal investigations, but also on the hundreds of other cellphones.
The law requires police to delete all non-target phone information within 24 hours and prohibits them from accessing data for use in an investigation not authorized by a judge. The American Civil Liberties Union of Illinois says it also prohibits police from using the tool to block phone calls or intercept calls, web-browsing or text messages.
A dozen states have adopted regulations, and Congress is considering legislation.
The bill is SB2343
