If these accusations against a US army "kill team" are true then the people involved should be executed.
Some of the activities of the self-styled "kill team" are already public, with 12 men currently on trial in Seattle for their role in the killing of three civilians.Five of the soldiers are on trial for pre-meditated murder, after they staged killings to make it look like they were defending themselves from Taliban attacks.
I don't believe these alleged actions are representative of our military people as a whole. I'm sure that the vast majority of Americans would be disgusted by these cold-blooded murders.
