I have no doubt that he said that and presented it that way, and in his own twisted mind he may actually believe it. Thing is, reality is almost the exact opposite of the FBI's statements. The public would understand. It would not misconstrue them at all. It would expose the conspiracy, and prevent future shootings by exposing all the markers of a deranged individual.
In short, the FBI must do all it can to hide the truth, which it has been doing with greater and greater frequency. It is 100% a political weapon of the left now. We don't have an "FBI" anymore. They are now the DNC Secret Police headed by a commissar.
