And as to the data mining that is forbidden the German agencies? Well, they helped NSA do so and took the forbidden fruit intelligence from NSA. If there is a violation there, it was the German agencies and the politicians that are responsible for their oversight that should answer.
As far as the spying goes, everyone and their dogs spy on Germany. That includes countries within the EU, Russia or China; you name it. Everyone knows this and has known it all along. Nothing has changed in that respect.
So the question seems to me quite a different one: Why are the US being singled out by German politicians and bureaucrats and why at this time?
