NYPD Wants More Surveillance Cameras Monitoring City

Shocker

Could more cameras in New York City help prevent attacks like the one at the Boston Marathon? That's what Police Commissioner Ray Kelly says the NYPD is looking into.

The department already uses so-called smart cameras that hone in on unattended bags, and set off alarms.

Kelly dismisses critics who argue that increased cameras threaten privacy rights, giving governments the ability to monitor people in public spaces.

 "The people who complain about it, I would say, are a relatively small number of folks, because the genie is out of the bottle," Kelly said. "People realize that everywhere you go now, your picture is taken."
