The last time we had military tribunals was when Lincoln invoked the Insurrection Act of 1807 after the incident at Fort Sumter in 1861.
My suspicion is that Trump expects an insurrection of social justice warriors, Black Lives Matter activists, SIEU members and anybody else Soros can mobilize when the arrests begin. He's expecting mobs to prevent the arrest of others when their indictments are announced. He's expecting California and other states to attempt unilateral secession, all of which would be sufficient for him to invoke the Insurrection Act and ask Congress for a declaration of martial law. Once that happens, military tribunals become legal.
No coup needed.
Or just don't follow the rules ...
thanks for your explanation, hopefully it won’t come to that.
