Currency Exchange, Howard and Paulina Streets, Chicago.
Below, a police camera, upper left corner of photo, monitors activity at this intersection.
These PODs (police observation devices) are all over Chicago now. And there are red light cameras everywhere and boot vans that drive the streets automatically processing license plates of parked cars to identify ticket scofflaws. Yet, in Illinois, it is a felony to audio record a police officer doing his job in a public place. This means, effectively, that you're also in deep trouble if you video record police encounters, unless you can show, after you've bailed out of jail, that you had the audio function on your video camera/cell phone disabled.
