Remember -- though the FBI did play criminal roles in Spygate, they were a front to get around the CIA's "no IS soil" rule.
The CIA is NOT DOJ. The PREDICATE was almost entirely CIA. Horowitz teed this aspect up perfectly for Durham.
The info they used to get the warrant -- info proven by Horowitz to be TOTAL BULLSHIT -- was orchestrated by the CIA in conjunction with foreign intel (again, not under Horowitz control).
