Big brother in the big apple [Surveillance]

Every Londoner is caught on camera on average 200 times a day, much more often than a New Yorker. Yet, terrorist threats - real or perceived - are changing US attitudes to surveillance. Due to major security concerns in America, the US is catching up to its British ally: about 3,000 cameras are being installed as part of the Lower Manhattan Security Initiative, a trend echoed in many other American cities including Dallas, Phoenix, Baltimore, New Orleans and Los Angeles. Also, New York City's Metropolitan Transit Authority (MTA) is in the midst of furthering a high-tech security upgrade, which began in 2006.
