Washington, Lincoln, Johnson, Wilson, Kennedy and FDR all used Military Tribunal courts, with which to prosecute people. If I had my druthers, EVERY last person in Afghanistan, connected wih OBL will be killed. Frankly, I don't care to have them tried anywhere.
Just WHY are you so upset by military tribunals ? Are you expecting that they will be used against you ? Since their is a 200 + year precident for them, ANY future president can decide to use them. Worry about that , if you care to.
