ACLU releases 1,800 'suspicious activity reports' on Americans gathered by terrorism officials

Civil liberties groups have released newly obtained documents that they say show innocent Americans being swept into a broad nationwide counterterrorism program.

The American Civil Liberties Union and several other organizations Thursday released 1,800 so-called suspicious activity reports that local law enforcement officials and others submitted to two California intelligence-gathering repositories called fusion centers.

The fusion center program was a target of a blistering Congressional report last year complaining that too many innocent Americans engaging in routine and harmless behavior have become ensnared in the program.

The ACLU and others are calling on the Obama administration to overhaul the program so that only activities with legitimate links to terrorism investigations are reported.
