commentary at The Christian Science Monitor by Mark Sappenfield: Can the military effectively investigate itself?
While I'd certainly not deny the military has had it's share of coverups, my knowledge of judge advocates is that once they start in on an investigation, they're like bulldogs. They'll be thorough and complete.
Not that I can say that much for the chain of command... but... in the end, I believe transparency will win out.
Even in this latest case.
