Spies everywhere you look

It seems that the domestic spying thing goes a lot deeper than the NSA and began at least as early as 2001. Via Raw Story, I came across this piece:

Official: Army Has Authority to Spy on Americans
By Jeff Stein, CQ Staff

“Contrary to popular belief, there is no absolute ban on [military] intelligence components collecting U.S. person information,” the U.S.Army’s top intelligence officer said in a 2001 memo that surfaced Tuesday.

Not only that, military intelligence agencies are permitted to “receive” domestic intelligence information, even though they cannot legally “collect” it,” according to the Nov. 5, 2001, memo issued by Lt. Gen. Robert W. Noonan Jr., the deputy chief of staff for intelligence.

So, I suppose if the Army can spy on us, so can the Navy, the Air Force, the Marines, the National Guard, and who knows who else? I guess FISA only applies to Democrats who might want to spy on Republicans.
