Today, a bipartisan Senate committee published the searing results of a two-year investigation (PDF) into “fusion centers,” which were created in the aftermath of 9/11 as places for state, local and federal officials to share and analyze information, in the hopes of detecting and thwarting terrorist threats.

The country’s 70-plus state and local fusion centers have “not produced useful intelligence to support federal counterterrorism efforts” and have “too often wasted money and stepped on Americans’ civil liberties,” according to the report, which goes on to criticize the Department of Homeland Security (DHS) for insufficient oversight.
