You're the one making a claim. The burden of proof is on you. Besides, I've already provided evidence. Maybe one day you'll open your eyes and stop being willfully ignorant.
Alright I will post it again:
But it is also plain that Congress long ago agreed to the president's power to convene military commissions (under U.S. Code, Title 10, Section 821). In addition, the president has inherent constitutional power as commander-in-chief to convene such tribunals, an argument acknowledged by Chief Justice Harlan Fiske Stone in a 1942 opinion. (Stone, writing for a unanimous Supreme Court, declined to set aside the military trial and execution of German saboteurs who had entered the U.S. to destroy war plants.) The president is also authorized by statute to write rules of procedure and proof for military commissions, and to decide whether or not it is "practicable" to adopt the ordinary rules of common law and evidence.
