Coombs cited Manning's Gender Identity Disorder, a constant topic throughout the hearing, and "the military's lack of response to that (as a) smack in the face of justice."
He read a letter Manning had written to his sergeant saying, "I joined the military hoping the problem would go away." Coombs then read three memos the sergeant had written where he highlighted Manning's instability.
"I assess that he is salvageable if he receives, and actively participates in, psychotherapy immediately," Coombs quoted the sergeant as writing.
The prosecution, however, steered clear of the topic, using the majority of its closing argument as a capstone to the evidence presented, citing forensic evidence linking Manning with Wikileaks founder Julian Assange.
"Manning was a United States intelligence analyst, who we trained and trusted," Fine said. "He used that training to defy our trust, and to systematically release over 700,000 documents."
As an analyst Manning had top secret clearance and was required to sign seven non-disclosure agreements.
Coombs concluded his arguments by stating that the "hallmark of a democracy is the ability of government to be open with the public" and that "sunlight is the best disinfectant."
He said that if individuals break the law because "they believe what they are doing is just, and they want to uncover unjust (and) arouse the public over injustice, they are really expressing the very, very highest respect for the law."
Until a decision is made, it is most likely that Manning will be transferred back to Ft. Leavenworth, Kans. As an active duty Army soldier, Manning will continue to receive pay and benefits while in pre-trial confinement.
