Would you stand before the judge, presenting as solid evidence, a report made in, what has to be considered, to put it mildly, a hurry?
Furthermore, would you, knowing that the President himself is expecting a certain outcome of the investigation, and, as you would probably know, was ready to, quite literally, fire you if the report didn’t fit his agenda. As you probably also know, that’s happened before to an FBI employee...
Now, would you?
