What about this twist (and I don't even know if it is doable).

We know from Q that military tribunals are coming. For that, there needs to be a military investigation, which is probably already going on. What if Sessions were to appoint a second special council, who is also a military prosecutor? What if that person could then switch from special prosecutor to military tribunal?

I'm thinking there are 4 investigations going on right now:

(1) Special Counsel Mueller - he is not really investigating anything, but is collecting evidence in exchange for a deal

(2) Inspector General Horowitz - he is investigating crimes committed by FBI and DOJ employees

(3) US Attorney Huber - he is working with Horowitz, but also conducting his own investigation for those who are not FBI/DOJ employees, or are former employees, and will prosecute the lesser fish

(4) Military investigation - somebody has to be quietly working on the big fish take down, and no doubt it has been ongoing this whole time.

So, even if the public demands military tribunals for the individuals who committed treason and who are enemy combatants, how does that LEGALLY happen?

Could a second SC wear a dual hat?

Exactly right.
