I understand in Illinois, permission to AUDIO record is required by both sides. The CPD has worked very hard to protect this law (based on old wire-tapping laws not relevant in the modern world) in order to make sure they are not recorded. Recently there has been some movement in state court saying that police in public doing their job have not expectation of privacy, so the law is not violated.
People have recently been prosecuted for recording police in public in IL, and the case law is far from settled.
(Note this all from my reading of news articles, and I have no legal insight into this).
