Audio Recording in Public Places Can Be Serious Crime in Illinois

Twenty-first century technology makes it easy to record events throughout the world, but that ease of recording may violate the law. In Illinois, making audio recordings of conversations in public places without the permission of everyone in the recording is usually a crime. Under the Illinois Eavesdropping Act, recording police officers can lead to a class 1 felony, which can carry a four to 15 year prison sentence. Illinois Public Media's Sean Powers reports on efforts to soften the eavesdropping law for both the public and police officers.
