Poll: Public backs more surveillance post-Boston

Americans strongly support increased use of surveillance cameras, which helped identify the Boston bombing suspects, Dzhokhar and Tamerlan Tsarnaev. Seventy-eight percent back having such cameras on the streets, with 16 percent fearing they would infringe on the public’s privacy.

More than half say authorities have struck an appropriate balance between security and privacy, with 26 percent saying the government has not done enough to address security concerns and 20 percent saying government measures have gone too far infringing on civil liberties.

The Tsarnaev brothers last month detonated two bombs at the finish line of the Boston Marathon, killing three and wounding dozens. Dzhokhar Tsarnaev, the lone surviving suspect, is in custody and has been charged in connection with the blasts.
