In this case, probable cause has been established, a Federal Grand Jury has been convened and a Federal judge has issued warrants all based upon the evidence that constitutes probable cause. You, as a private citizen, may not be aware of the exact nature of that evidence but that does not mean it doesn't exist. You have elected representatives in the House and the Senate whose job it is, among other things, to check up on these sorts of things. You don't trust Mueller? You don't trust the FBI? You don't trust the House or the Senate or the DoJ? That begins to be a different sort of problem altogether.
