Your right, I only posted a portion of what I found about secret surveillance and didn’t even touch the Patriot Act or FISA.
May the Fourth Amendment to the Constitution (1789-2001) RIP!
I am sure the people who passed it were sincere, as are many of the people who use it, the FBI, the judges. But whether sincere or not, FISA doesn't curtail warrantless surveillance in the least. See Bush's "Terrorist Surveillance Program," wholesale interception of domestic communications. Still going on, with reams of classified legal argument and statutory changes being made to provide cover or make the perps feel better.
If the public knew the blunt facts of the matter, it would be angry.
