Video surveillance is big business. Expect it to get bigger. After law enforcement used closed-circuit television (CCTV) cameras to help identify last week’s Boston bombing suspects, lawmakers and surveillance advocates renewed calls for increased numbers of cameras nationwide.

“We need more cameras, and we need them now,” ran a Slate headline.

Rep. Peter King (R-NY) agrees. In an interview the day after the bombings with MSNBC’s Andrea Mitchell, he called for more video surveillance so that we can “stay ahead of the terrorists.”

“So yes, I do favor more cameras,” said King, who sits on the U.S. House Homeland Security and Intelligence committees and has also called for increased monitoring of Muslim Americans. “They’re a great law enforcement method and device. And again, it keeps us ahead of the terrorists, who are constantly trying to kill us.”

Law enforcement officials in New York are almost certain to oblige. NYPD Commissioner Ray Kelly wants to “increase significantly” the amount of surveillance equipment in Manhattan, which already has one of the country’s most robust systems.
