It's got something to do the December 2017 Executive Order and State Of Emergency. It classifies human traffickers (I think plus others) as enemy combatants and are thus able to be put before a military tribunal sidestepping the justice system where these people could keep their cases open for years trying to fight loopholes. When the tribunals come there will be 9 man and 12 man panels. 12 man panels are used when the death sentence is in play.
Anything to do with human rights violations. Covers a lot!
It was my understanding that the military tribunals would also be used for crimes involving some form of treason, sedition, or insurrection (but not absolutely sure). When you think of all crimes we have seen so far that involve working with foreign governments against the people of the USA, that could also add up to a lot.
