I see a picture of US Soldiers trying to save the life of a farmer boy that was accidentally shot, you see pictures never tell
the whole truth, it always depends what your believes are.
You see pictures never tell the whole truth but they do lend a hand to the deductive reasoning explained in just a few pictures of a wounded man, and American Medics.
So, even in that scenario you don't know who shot who, but you do know that the American Medics are lending a hand to save a life.
