Per Snowden's interview, which is very believable on the face of it, there are no controls on many analysts who are free to delve into recorded data on the lives of anyone they feel like for whatever reason, including personal vendetta or whatever. I personally find this to be very believable. And anyone who thinks this alleged minimally supervised power wasn't being used in a nefarious way by the Chicago thugs in this regime on a daily basis is deluding themselves. All enabled by either delusional, monster-protecting dupes, or criminals (you pick), like King.
NSA was chartered to spy on other nations, NOT the US. The FBI is the only agency that can spy on the US:
section 2.3, ....Collection of Information..... included in Executive Order 12333-United States Intelligence activities,.......specifically limits the NSAs collection of data to foreign intelligence or counterintelligence sources,.....
.....further stipulating that data collection within the United States”shall be undertaken by the FBI or, when significant foreign intelligence is sought,......BY OTHER AUTHORISED AGENCIES OF THE INTELLIGENCE COMMUNNITY.......provided that no foreign intelligence collection by such agencies may be undertaken for the purpose of acquiring information concerning the domestic activities of United States persons.”
It is ILLEGAL!
However,.....’Snowden made it clear they hire out many Other agencies who do not have the regulations and laws.... and so ...there you have it!
