NEW YORK, NY September 30, 2007 —Newark, New Jersey is installing more than 120 surveillance cameras, and a gunshot detection system, connected to a wireless computer network. Mayor Cory Booker calls the move "an evolutionary tactic in crime-fighting."

The city is still recovering from the execution-style murders of three college students last month. When the schoolyard shootings occurred, Booker and local civic and business leaders had already scheduled a meeting to discuss a so-called "community eye" system.

The Newark Community Foundation is raising $3.2 million to pay for the gunshot detection system and most of the cameras. Critics say the system involves an over-reliance on technology, and civil liberties advocates have expressed concern that privacy rights could be violated.
