I do. A military court is subject to judicial oversight, just like a civilian one.
There is oversight. The men can have civilian counsel and they will be assigned a military counsel as well. Should these men be convicted in a general court martial then their case will be appealed automatically to the Navy Court of Criminal Appeal. If that court upholds the sentence then they can appeal further to the U.S. Court of Appeals for the Armed Forces. If that court upholds the lower court rulings then they still have a chance to take the case to the U.S. Supreme Court. Other than that what do you want done?
