CHICAGO (AP) - Governor Quinn has signed a bill into law that he says will protect people's right to privacy.
The new law signed Tuesday will regulate the use of drones by law enforcement.
Drones are sophisticated, unmanned aircrafts that authorities are considering for aerial surveillance.
The law requires authorities to obtain a search warrant before using a drone to collect information.
Still, there are some privacy concerns.
They can use it for traffic crashes, to look for missing people, monitor even busy intersections and that's where you get to the problem of once that little chopper is up in the air whatever it sees, doesn't just disappear," Ben Yount from IllinoisWatchDog.org said. "There are real privacy concerns every time you put an eye in the sky."
The American Civil Liberties Union praises the new law as appropriate and reasonable.
The legislation also outlines a few exceptions, including when the Department of Homeland Security decides surveillance is needed to prevent a terrorist attack.
