Chicago Mayor Richard Daley announced a new municipal surveillance system that will use 2,000 remote-controlled cameras that "are the equivalent of hundreds of sets of eyes."
The American Civil Liberties Union warned that the federal government has been using corporations to carry out surveillance of citizens because private firms are not subject to many privacy and civil-liberties laws.
A report by the General Accounting Office found that government agencies are engaged in at least 199 data-mining projects, 36 of which involve personal information taken from private sources.
