I’ve pretty much come to the conclusion that these investigations are going nowhere because the Clinton Foundation was a money-laundering front for the CIA.
First tier is of course political support & direction, which explains Clinton, May, Macron, et al. Secondly are the intelligence & police organizations, such as the CIA & FBI, which ignore/circumvent all established judicial procedures not in agreement with their mandate. The media, being a very important element of the control profile, are then incorporated for full saturation conditioning.
If you step back and look at the big picture, then it all begins to make sense. The Clintons have no more real power than any other individual. As long as they're good in the organization, they're protected. Like a hive, individually no one is that prominent on their own, but they are safe if they stick to the script.
This is essentially why following and/or getting exercised about each daily reveal is completely futile. There is only one way out of this box, but Trump isn't going there. Therefore, it makes much more sense to bet on the obvious outcome.
