First one I saw was a female senator just incredibly angry at the generals sitting there. She gave them a telling off sans swearwords (but felt) about "you demandec to retain authority over these cases and I am sitting here with 5 years worth of testimony and witnesses. Who is being held responsible? Show me! And who is held respinsible when the person in charge fails in their duty? Who? Anyone? What exactly have you done? Show me!" And the general looked a little embarassed. "I dont have a good answer for you and I'm not going to sit here pretending I do."
Which is...wtf kind of an answer is that??
Then senator Mccain started his time adderessing the generals. Only he went the route of "Americans are duly proud of our marines. They represent our best values. They are our finest, bravest young men dedicated to serving our country." (Paraphrasing...go with it.) "The security of our country and our military rests in our soldiers sharing those common values and the mutual trust they place in each other. Anything that undermines that must be dealt with. It is the responsibility of our commanders to maintain discipline..." Etc.
Aka he went the patriotic/duty/pride route. Which made the generals squirm.
I really should keep that kind of tactic in mind. "Of course we stand behind you 100% because you are awesome. There's this thing that is kinda smearing your honor...which you're going to fix because you're awesome and honorable."
