Excellent analysis. Read the charge to the FBI. Paraphrase: They are to look into credibility of the acquisition and the reliability of the person making them. Someone suggested that Flake may have been the Judus goat leading the democrats into the evaluation of not just Kav but also each of the other accusers They wanted an FBI investigation give it to them in shades.
I believe the good guys already have all the information they need and more. I bet they already know what kind of toothpaste she used in high school. The questions they asked in the interrogation told me that! Remember the saying: never ask a question if you don’t know the answer.
The good guys have the goods. Hard evidence. Now, because of Flake, it will be the FBI who will be the bad guys.
Assuming we can trust the FBI. ;-(
