Or you know, they could have hired a competent guy like Mueller to do an investigation? No? You do know that all the prosecutors and judges for Trump were picked by Heritage - and nothing can get more establishment than that corrupt organization funded by the elitist of the elite.
You can't have it both ways, defend them and then whine about the establishment.
It has nothing to do with Mueller's competence, he has the wind at his back in this case. Had he been investigating the aforementioned, it would have been like he was on the Edmund Fitzgerald.
