In new documents just revealed, it
turns out that the NSA has been feeding information that it uncovers from this massive surveillance to the Drug Enforcement Agency.
This is a good example of what I meant in
the original Snowden thread with '
as soon as the various datasets and capabilities are linked, there is virtually no privacy left'. In this case the problem is caused by willfully ignoring sensible legal and procedural restrictions by the NSA and other government agencies. In other cases, database combination is (or should be) limited by law for equally important reasons. But breaking or bypassing these restrictions invariably diminish privacy and freedom, of which there is only so much to go around.
