Sam's Smooth Talking

Sam's trying to lighten Dean's guilt. Dean couldn't have known Jess was going to die and he didn't directly kill Jo, so Dean's just got to believe that. He doesn't, but he's good at pretending, though. I'm not sure I like Sam's way to approaching this case. Yes, he's showing the traits of a good lawyer, manipulating and twisting the testimony so it fits his case, but he's also just forcing the issue of "it's this way because I say it is, so you say it's this way, too."
