Like I say, this is all starting to look a lot like Modified, Limited Hangout.
Let us assume that Barr is not all that we hope he is, is he well advised to continue making dark comments about "spying" and permitting inferences that the stories he's getting from the FBI our not "hanging together?" I think he is quite consciously creating expectations that he would be foolish to do if he intended only to disappoint.
On the other hand, I can see that he might want to pretend at this point to be a fearless Knight Templar assaying only to do justice so that when he waffles later on he has a basis of credibility as cover. That it seems was the pattern of James Comey. I do not want to appear naïve but I find this last scenario unlikely to be the modus operandi of Atty. Gen. Barr.
