Communications and Public Policy Director Ed Yohnka discussed the ACLU's concerns with the use of "stingray" technology by the Chicago Police Department (CPD) in a recent segment on WBEZ. Stingrays operate by mimicking a cellphone tower, and have the ability to access their owner's locations and other identifying information. Given the potential threat to privacy that the use of such technology by law enforcement has had in other states, the ACLU of Illinois will continue monitor the issue. Ed Yohnka stated:

“We know that this technology has been used in connection with protests in other places,” Yohnka said. “I don’t know whether or not that’s been used in Chicago. I would say that if this technology is being used to track people, if there are technologies that are being used to collect large swaths of communication, those are things that are very troubling and very wrong and I think people would rightly be concerned about them.”
