PHOENIX -- Investigators examining surveillance and amateur video are hoping to find a clue that leads them to the people responsible for the Boston Marathon bombing.

Video helped solve the London subway bombing and New York City officials credit their extensive network of cameras for preventing and solving crimes.

"So I think it shows we do need more cameras," Rep. Steve King (R-NY) said Tuesday. "We have to stay ahead of the terrorists."

The ACLU has protested the expanding use of surveillance cameras by cities, police departments and school districts. The organization cites privacy and racial profiling concerns, among others.

"Privacy is always a concern, but really, if you're not doing anything wrong, then you don't have anything to be concerned about," said Tom Vigilante, who owns Centralized Vision.

"The amount of cameras being placed in greater Phoenix is growing at a rate beyond comprehension," Vigilante said. "Cameras are more affordable than ever. The technology is well beyond where it's ever been."

His company monitors roughly 5,000 cameras at businesses, schools and other buildings. He said his staff helps police make several arrests a month.

"It's safe to say somewhere somehow you're being watched," he said.
