Organizations are made of people, at all levels. You are not trusting or not of an abstract entity, you are dealing with a lot of people that you don't know from the present and the future, any of them that can use or abuse of the information they are gathering, in individual level or more related to policy level, or act based on that information.

Also it is not about crime, is about control, for whatever agenda they have now or later. And the lack of Snowden level leaks in 7 years hints at which point they have control now.
