Legislation that would require police forces in Illinois to get a warrant before using surveillance equipment to covertly scan people's cellphone data is headed to Gov. Bruce Rauner's desk.
The Illinois Senate unanimously passed the legislation last month, and the House followed suit Wednesday.
The equipment in question, often called "Stingray," acts like a cellphone tower and is typically attached to police surveillance vehicles. It can collect data secretively from nearby cellular devices.
Under the proposal, police would be prohibited from keeping data captured by the equipment if it comes from an individual not under investigation.
