Fighting Terror and Protecting Civil Liberties

Some 4000 federal, state and local organizations are battling domestic terrorism, far more than the number of terrorists who've been identified. The FBI is amassing data on US citizens who've never committed a crime. Local agencies monitor anti-war groups and Tea Party meetings. The Department of Homeland Security is spending tens of billions of dollars, more money than it can keep track of, and local agencies and "fusion centers" are happy to snap it up. Is fear breeding over-reaction? Are Constitutional rights at risk? Will the US develop a coherent intelligence strategy or become a police state?
