They need to do that anyway -- Murtha and the MSM are egregiously beyond the pale.
Let the investigative chips fall where they may. But if it turns out that Marines committed atrocities, then we should be very careful that we don't allow our antipathy toward Murtha and the MSM to blind us to things that are wrong, just because Murtha and the MSM pointed them out to us.
Agreed, the chips need to fall where the truth actually is.
But the MSM and Murtha are not going public with these leaks to improve or keep the integrity of the Marine Corps. It's just the opposite, they are gleefully giving the islamo-fascists aid and comfort. So that even when the investigation shows there is far less culpability than was portrayed, the damage will have been done.
