Chloe asks Lt. Johansen during the 'trial' - isn't there a simple forensic test which could determine if Young fired that weapon, and she answers that there is. This is not actually correct - firearms discharge residue (FDR) that cannot be typed to an individual weapon, and so would not provide any conclusive evidence, especially as Col Young is a soldier and all crew members have been in contact with people who use firearms. The high concentrations of FDR required on Col Young's hands to show he had personally fired a weapon recently would have deteriorated in a matter of hours, even quicker if he washed his hands, and could not have produced results by the time of the trial.
Franklin: Guess I should be thankful there's no cavity search.
Scott: That can be arranged, Franklin.
Camille: Sergeant Greer has to be your number one suspect.
Scott: So he killed Spencer, ran away to hide the gun, then went back and called it in? Besides, if he did do it, you'd have no evidence at all.
Eli: Not helping your argument...
Young: I can't investigate myself, Lieutenant. You can't be asked to investigate your immediate superior officer. That leaves Wray. We're gonna have to play this by the book.
Scott: Well, with all due respect, sir, if the book covers this, I missed it.
Caine: I tell ya, if I could change one thing about the day we escaped from Icarus, I would have worn better shoes.
Volker: Really? Those are nice shoes.
Rush: Well, you're the wrong man for the job, Colonel. I'm sorry to have to be the one to say it but I think you know it's true.
Young: Do I?
Rush: You don't believe in the mission. You resigned your position as SG leader because you didn't wanna make the hard decisions, the life and death decisions. Well, that makes you a liability. I'm not proud of what I did, but I did it for the benefit of everyone on board.
Young: The end justifies the means.
Rush: Yeah, something like that.
Young: Are we done?
Rush: We will never be done.
