Prove what? Prove that the same military courts who can convict and execute a Soldier of aiding the enemy for something as small as giving an enemy agent a TM that is available to the public went soft?
The proof is in his actions, which were reported by fellow Soldiers and family. He is a homosexual who, according to his councilor in Iraq, questioned his own gender. He was even considering sexual reassignment surgery. During Basic Training, he couldn't hack it, and was scheduled for a failure to adapt discharge, but his discharge was denied. He was constantly harassed, and became insubordinate. He was openly gay. He had a troubled relationship with his boyfriend, which caused him to be referred to the mental health facility due to claims that he was emotionally unstable. His superiors even wanted to leave him in Ft Drum because he was "a risk to himself and possibly others,". In an interview with a school reporter he had during a homosexual marriage rally, he said "I've been living a double life. ... I can't make a statement. I can't be caught in an act. I hope the public support changes. I do hope to do that before ETS". Because of all this, he felt isolated. He didn't have any friends in the Army, and this angered him. It doesn't take a genius to put two and two together. I have seen the same thing in the Army. Some Private can't hack it, they get mad, they lash out, ostracizing themselves from their peers, and eventually they end up doing something very stupid that either gets them arrested or kicked out with a bad conduct discharge. Manning was a piece of ****, he didn't belong in the Army, and he sure as hell didn't belong anywhere near classified materials. It was only a matter of time before he did something idiotic, and then he did. He didn't do it because of patriotism, or because he was an outstanding human being. He was mentally ill, he was angry, and he had a personal vendetta against the Army, and the US for not granting his majesty the right to marry another man who didn't want to have anything to do with him.
