Gaps in Video Security in New York Subway System

A recent homicide in a New York City subway station without closed circuit security cameras underlines the importance of these types of security methods -- both for investigation and prevention.

"More than eight years after the Sept. 11, 2001 attacks, the subway's video surveillance system, one of the key tools the city has in deterring and investigating attacks of any and all kinds in the subways, remains a patchwork of lifeless cameras, unequipped stations and problem-plagued wiring.

The need for them was highlighted on Monday as the police tried to solve the weekend homicides, while also increasing subway patrols in response to the rush-hour bombings in the Moscow subway system, which left at least three dozen people dead."
