Unfortunate Shooting in Afghanistan

I am a retired infantry soldier and have a good idea that this soldier acted alone because of a mental defect or stress. When and if he is tried for these crimes and found to be guilty he will be punished. However, the trial should be in the US not in theater. I can only imagine if he is tried and convicted there. The local populace would demand to be the executioner. Of course getting him out of country will place the soldiers left behind at grave risk of retribution as a result of the anger that will continue to spawn going forward. I too agree we should leave Afghanistan. Our mission of destroying or breaking up Al Qaeda is as complete as any killing of a multi-headed Hydra can be. The people of Afghanistan do not want us there and no matter how long we are there to train, arm and feed them they will not adopt the principles of democracy because of the culture, let alone thank us for the schools, hospitals, roads, water wells, etc we have built for them. I am just sorry that we have expended great resources from our nation’s youth to little or no avail.
