Once again, an a junior officer who knows enough to rat out more senior officers scates.

Capt. Lucas M. McConnell of Napa was granted immunity and ordered to cooperate with officials looking into the November 2005 killings, the Marines said in a press release.

….

Lt. Gen. James Mattis dismissed dereliction of duty charges against McConnell on Sept. 12. and determined that “administrative measures” were an appropriate punishment, the Marines said.

Seriously.

A sergeant gets jail, but a captain, who would be in a position to finger a colonel, who might in turn finger generals…nothing.

This is an excercise in ass covering.
