Some object to the presence of cameras based on misplaced concerns over privacy and civil liberties. But they should be reminded that the Mall, for example, is a public space, and a police presence there is just as likely as a camera to limit privacy.

No. Police are not always looking in every direction and they do not have a perfect memory. Furthermore, it sounds like they have about the same impact as police presense... Of course, the more invasive measure is preferable because its cheaper... I'm glad to hear him discredit youth cerfews though.
