I don't like when we all get blinded by trying to define people as white hats or black hats. In this situation it's best to look at people as tools. When they're useful they're up to bat. Some will always be "white hats". Some will have to become convinced to become a white hat. Some will be known black hats that we use to get to the next point in the mission.
Jury's still out on where Pompeo fits into this. That article of course makes it appear he's a black hat. But maybe kaNSAas knows exactly what strings to pull to get him to act on our behalf. Or maybe they're just gathering intel. We shall see…
