Most Americans have gotten used to regular news reports about military and CIA drones attacking terrorist suspects - including US citizens - in Pakistan, Yemen, and elsewhere abroad. But picture thousands of drone aircraft buzzing around the United States. By some government estimates, as many as 30,000 drones could be part of intelligence gathering and law enforcement here in the United States within the next ten years. Operated by agencies down to the local level, this would be in addition to the 110 current and planned drone activity sites run by the military services in 39 states, reported this week by the Federation of American Scientists, a non-government research project. Civil libertarians warn that "unmanned aircraft carrying cameras raise the prospect of a significant new avenue for the surveillance of American life," as the American Civil Liberties Union put it in a report last December. "The technology is quickly becoming cheaper and more powerful, interest in deploying drones among police departments is increasing, and our privacy laws are not strong enough to ensure that the new technology will be used responsibly and consistently with democratic values," reported the ACLU. "In short, all the pieces appear to be lining up for the eventual introduction of routine aerial surveillance in American life."
