Florida company Seisint created the 120,000 person database which is being used to stop terrorists from moving through the borders and airports of the US. Some investigations and arrests happened thanks in part to the list. Seisint heads the Matrix.

A "terrorism quotient" was used to create the list. High scores were given to people based on having "dirty" addresses that other suspects shared, gender, age, ethnicity, "investigational data," credit history, pilot/driver licenses, etc.

Civil libertarians and members of the 2 major political parties became alarmed because people never convicted of crimes were put on the list. Seisint stopped the scoring system in 2003. A FL police official says: "we didn't want anybody abusing it."
