Really the whole team will ALL be in trouble if Ray says 'murder'
How so? The only ones who know actually know something are Ray and Brass. Catherine and Sara had their suspicions, but without the cuff and/or an admission from Brass, there's really nothing they could've done about it; Catherine was forced to sign off on the report because they didn't have anything else. Standup guy that he is, I think Ray will go with 'self-defense' and cut his losses and quit before he allows anyone else to go down with him for something he did.
Ray- murdered Haskell
Brass- covered for Ray by getting rid of the evidence- the cuff
Catherine- she's in charge so the person in charge usually gets some heat, really Ray never should have gone to L.A. but it wouldn't have mattered, he probably would have still gotten on a plane
Al- how much of an autopsy did he really do?
Greg and Hodges- should have reported Ray in Cello and Goodbye, and Hodges gave Ray his password
Nick- going all cowboy in L.A.
Sara- don't think she did anything wrong, correct me if I'm wrong
They reported self defense and yes they didn't quite have all the evidence but still imagine how in court lawyers from then on could spin all this if Ray says he did it or whatever might happen in the premiere
