Armed with the latest information, police will be better able to catch crooks and spot criminal trends. But in this digital age, with so much data available about individual Americans, the lines between what is acceptable investigation and what is intrusive spying can quickly grow unclear.

Using "data mining" technology, its search engine ripped through billions of public records and matched them with police files, creating instant dossiers. In the days after 9/11, Matrix researchers searched out individuals with what they called "high terrorist factor" scores, providing federal and state authorities a list of 120,000 "suspects."
