Federal Officials Create Vast Troves of Data on Individual Americans

Several thousand law enforcement agencies are creating the foundation of a domestic intelligence system through computer networks that analyze vast amounts of police information to fight crime and root out terror plots. As federal authorities struggled to meet information-sharing mandates after the Sept. 11, 2001, terrorist attacks, police agencies from Alaska and California to the Washington region poured millions of criminal and investigative records into shared digital repositories called data warehouses, giving investigators and analysts new power to discern links among people, patterns of behavior and other hidden clues. Authorities are aware that all of this is unsettling to people worried about privacy and civil liberties. Mark D. Rasch, a former federal prosecutor who is now a security consultant for FTI Consulting, said that the mining of police information by intelligence agencies could lead to improper targeting of U.S. citizens even when they've done nothing wrong.
