Illinois StingRay crackdown
The state of Illinois is making it harder for cops to use StingRay devices, which mimic legit cellphone towers to track people's whereabouts.
A new bill will forbid police from using the surveillance equipment on any investigation that has not yet been authorized by a judge.
The law also calls for police to delete collected StingRay data on any individual who is not part of the investigation within 24 hours.
The bill, SB 2343, was signed into law by Governor Bruce Rauner on Friday. ®
