Im not ready to give Mueller a pass yet. Its possible that he was trying his best to find dirt (Consider is plea deal offer to Corsi, whom Mueller didnt even end up indicting.) but the clock ran out on him when Barr was appointed. Muellers ambiguous obstruction non-conclusion was the best that he could do. He could have just said what Barr and Rosenstein said.
Good points that I shall keep in mind.
Time for Trump to go on the offensive. Lets find out how the FBI and Mueller investigation came about. And detail the human wreckage that resulted from the Mueller anal probe.
Mueller was just helping his buddy Comey on not clearing Trump on obstruction.
