Sorry If I wasn't very clear there.
No one has been charged. They should be.
We have LE's admitting that they lied. If you lie in testimony, that is called PERJURY. It doesn't even have to be proven, when you admit to it.
They were not testifying - this information was sealed - Judge Mudd ruled that their statements were not admissable in court.
Have you confused these hearings with the actual trial?
