health records. Furthermore, this information is databased and maintained indefinitely by the FBI. Previous legislation required that federal law enforcement destroy any records harvested during an investigation that pertained to anyone deemed innocent. The Patriot Act superseded that and now the records are maintained indefinitely. According to the legislation, they may be "shared with third parties where appropriate" yet nowhere in the legislation does it define who these third parties are or what conditions would be deemed appropriate for the sharing of such records. The large scale wiretapping and tracing of calls to and from foreign countries also falls under this. Millions of phone records were harvested, fed into a database and were searched for patterns of calling to and from numbers of known terrorists.

The associate art professor, who works in the biotechnology sector, was using benign bacterial cultures and biological equipment in his work. Police arriving at the scene found the equipment (which had been displayed in museums and galleries throughout Europe and North America) suspicious and notified the Federal Bureau of Investigation (FBI). The next day the FBI, Joint Terrorism Task Force, Department of Homeland Security and numerous other law enforcement agencies arrived in HAZMAT gear and
