I think that this is such a relevant and interesting topic, I decided to bump it back up to the top of the discussion board.
When I was in high school, I was fortunate enough to go to a presidential library and browse through the declassified files of that administration. I was incensed to discover that long before WWII so-called American citizens were being spied on and massive amounts of information was being documented an stored on non-violent organizations. Organizations such as the Pullman Porters, A. Philip Randolph, alleged Communists in the black community (which is code for blacks trying to gain equal rights in America). These were files from the FDR administration. I would not be surprised if the spying had indeed not stopped at all, even after the Church commission of the late 1970's.
As a matter of fact, due the lack of laws that are lagging behind the increase of rapidly changing technology, it has become a loophole of sorts for the government or unscrupulous people to take advantage of "spying" on people.
In regards to this so-called investigation, the story was put on hold for a year, and they couldn't investigate who leaked it when it was first brought to the attention of the President? Yet he could ask for the press not to release the information for a year? I smell BS
