Chicago to get 'plugged in', page 1

Chicago will soon become a locked down city with camera's across the city - ranging up to 2,000 camera's. Is this sort of security required by Chicago and other major U.S cities? Interesting question I think they could be useful in certain situations but 2,000 is alot! What do you guys think?

EDIT: sorry guys this was already covered

Mayor Richard Daley yesterday revealed plans to put up at least 250 new snooping cameras around town. These will be linked in to similar systems set up by the police and fire departments, parks management, public school system and others, giving the city more than 2,000 cameras to watch the public. Most of the new cameras will be placed downtown.

"The overall objective of this program is to make the city a safer place for its citizens, communities and assets by continuing to find ways to protect our critical infrastructure while providing a managed environment," Daley said at a news conference.
