And who would it advantage for them to go public.
Not the snitch. They value their lives.
Not the investigators. They value their investigations.
Given that, how do you know anybody hasn't provided testimony?
You don't. You're not on the need to know list.
I swear, you beyond the trees peoples....
Think.
The snitch and the investigators are not the only parties involved here.
These people all have dirty hands in this and they all know of their joint complicity. The deep state playbook is to seek immunity first in the court of public opinion. It is my opinion that if any of the players in this really feared the investigation, they would be overtly or covertly feeding the media (dis)information to distance themselves from the others. The fact that they are holding tight, and maintaining the talking point that the Barr/Durham investigation is a goose chase, leads me to believe they fear nothing.
Simply put, this was a tightly orchestrated coup attempt. They all know that if one goes down, the rest would likely go down with them. The fact that they are not turning on each other, suggests to me, their confidence that nothing will come of this.
Like I said, I hope I am wrong, but I'll believe it when I see it.
