Well, at least we know where you get your information.
You don't need a special prosecutor to investigate HRC or Comey. Both are out of government. If you want, you can call your local FBI office and make a complaint. They would be the office handling citizens at this point.
For what it is worth, and I'm just throwing this out there. It is possible that Trump and some in his orbit, will be cleared of any criminal charges in this "matter." Not innocent, just not charged. For the same reasons as the Clinton email investigation resulted in no charges being brought. It maybe that the case will be difficult to prove, largely from an evidentiary perspective since much of the evidence is classified now. Which means conviction will be difficult. The government likes to win cases. Unlike Congress which enjoys the spectacle of the investigation.
You can argue, from a legal standpoint, that the Trump's are just as "stupid" as Comey claimed Clinton was when it comes to the law, no?
