For me it's a tough call. Chief obviously was wrong but they are all under a great deal of mental and physical stress. I definitely think he's guilty and needs to be punished. The situation is dire and mistakes like that can't be tolerated. And let's face it, he basically put the final nail in Galactica's coffin. Maybe if they put him in a room with Starbuck for a month and if he can go the whole time without her killing him, he deserves to live.
