The CNN story that he did not blame the troops was based on a mistranslation of his statements. He said that either it was intentional or else the troops are just scared boys blasting everything they see. But he never said that he didn't blame the troops.
Thanks for the clarification.
So it's clear from his most recent statements that he thinks this was intentional. I still say we (the U.S.) should hang back and investigate responsibly while not saying too much and let this reporter and her friends make ever wilder accusations. It's not making them look good.
