Why? Why does knowing where it is located a "right"? I feel US citizens have a right to know who is storing the data, and the parameters they must follow. Also you should have a right to know where the data is located, as in "in the USA". But beyond that, isn't having the actual address a security concern?
The public is far more at risk with the CIA around to begin with, so long as it continues to carry out bullshit interventions around the world that so often come back to bite us. The primary impediment to enumerating these risks is the CIA's lack of transparency.
