The authorities of United States have a long history of spying on 
those who actively participate in the nation's democracy through free 
speech and other civic and community activities.  Over the years, 
citizens and the judiciary have tried to rein in state surveillance by 
asserting First Amendment protections of free speech and Fourth 
Amendment protections against unreasonable searches and seizures.  From 
the Palmer Raids through COINTELPRO, periods of perceived national 
emergency have typically eroded these protections.  Today, a sprawling 
industry has mushroomed, financed by taxpayer money, ostensibly to 
protect the nation from terrorism and other threats.  As this industry 
consolidates and grows, sophisticated surveillance technologies pose new
 threats to privacy and the right of association.
