Police in Florida are creating a counterterrorism database designed to give law enforcement agencies around the country a powerful new tool to analyze billions of records about both criminals and ordinary Americans.
Organizers said the system, dubbed Matrix, enables investigators to find patterns and links among people and events faster than ever before, combining police records with commercially available collections of personal information about most American adults. It would let authorities, for instance, instantly find the name and address of every brown-haired owner of a red Ford pickup truck in a 20-mile radius of a suspicious event.

Some civil liberties groups fear Matrix will dramatically lower the threshold for government snooping because other systems don't allow searches of criminal and commercial records with such ease or speed.
