Privacy activists met in front of the federal building in San Francisco to call for the dismantling of regional intelligence hubs known as fusion centers. The centers facilitate information sharing between local, state and federal law enforcement agencies. The activists say fusion centers create an unprecedented level of information awareness that threaten civil liberties. Rallies were scheduled today in Washington D.C., Los Angeles, Oakland, Chicago, Boston, Dallas and Charlotte for a national day of action. Nick St. Charles filed this report.
