Why
These have been reauthorised long enough to be able to show results but the NSA can't give an example of their success.
These have repeatedly overstepped their authorised purpose and seem to be unable to correct this.
The NSA don't have any appetite to fix the issues with the programs.
The DNI (and other "intelligence" staff) repeatedly lie to or stall replying to Congress and the Senate.
The question has to be Why on earth would the senate ever reauthorise this legislation permanently?
Also, If I so blatantly lied to Congress or the Senate I would be thrown in jail why haven't these liars been punished?
