I'm pretty certain Q is clear about what's going to happen, the civilian justice system is going to fail but then Trump is going to have the military finish the job. Q has always been about the military, barr is just a distraction and the final piece to show how badly our justice system failed. Think about the Trump calm before the storm comments, who was he surrounded by? Generals.
I don't have specific Q posts off the top of be head to point to but I'm getting a strong feeling that what will happen is the DOJ refuses to do it's job and then Trump will involve the military to do what they wouldn't. Trump is going to take all the blame / attention from this and do what barr wouldn't with he help of the military.
Reading your post to infer Barr is following the Q/Trump plan and letting the corruption expose itself within the DOJ/FBI by not taking direct action... allowing the puppet masters to pull the strings of the remaining agents and sleepers and take last "legal" attempts at coup within those two organizations in full view of American public before any kinetic action.
Concur with courts martial conclusion.

Also, Lindsey asked Kavanaugh about military tribunals in one hearing.
And Gitmo is run by the military and it won't have civilian courts.
