The WSJ has a good article up about surveillance cameras up on the streets of Chicago:
A giant web of video-surveillance cameras has spread across Chicago, aiding police in the pursuit of criminals but raising fears that the City of Big Shoulders is becoming the City of Big Brother.

The networked system is also unusual because of its scope and the integration of nonpolice cameras.
The city links the 1,500 cameras that police have placed in trouble spots with thousands more--police won't say how many--that have been installed by other government agencies and the private sector in city buses, businesses, public schools, subway stations, housing projects and elsewhere. Even home owners can contribute camera feeds.
