Suicide Prevention in the Army (or lack of).

On December 16th, a funeral was held for the recently deceased 27-year old Staff Sergeant David Senft.
While this was a time to say farewell and commemorate the soldier, it was also a time that several questions were left unanswered regarding his untimely death. The Army stated that Sergeant Senft was found at Kandahar Aid Base and had died due to "injuries sustained in a noncombat related incident." As of now, no one has announced a specific cause of death. David's father, on the other hand, believes that his son committed suicide, and he's not the only one who believes so; many of David's friends and family members, as well as soldiers who served side by side with David, agree with his father's assertion. According to the email that was sent by the Army's Criminal Investigative Division to David's father, David was "found dead with a single bullet hole in his head, a stolen M-4 automatic weapon in his hands and his body slumped over in the S.U.V." Not only this, but David's cellphone was found lying next to David with a displayed message that read, "I don't know what to say, I'm sorry." And yet the Army still claims that the cause of death was otherwise.
David Senft first tried to commit suicide at Fort Campbell, Ky. His second time was at a mental institution that he was sent to by the Army. Despite these attempts, these cries for help, the Army nevertheless declared that he was "fit for duty" and shipped him off to Afghanistan to fight. There, he was forced to meet with on-sight counselors to help him cope with his troubles adjusting to his new surroundings.While Defense Department officials have often declared suicide prevention a top priority, it is clear that they are either very unsuccessful, or simply not trying hard enough/ignoring the problem. I'd bet on the latter. It was very clear that David was in no shape to be deployed, and yet he was anyway. Why wouldn't the Army make it their best interest to see fit that their soldiers, who are essentially the heart of the entire organization, are in their best shape, both physically and mentally? David's father asks, "I question why, if he was suicidal and they had to take away his gun, why was he allowed to stay in Afghanistan? Why did they allow him to deploy in the first place, and why did they leave him there?"
What do you guys think?
