Hobbs at Trial *spoilers*
***Spoilers***
Awesome film, but I am confused by Hobbs at the trial.
It is obvious he had profound respect for Captain Sawyer and hatred for Horatio.
So I am trying to put this in order:
Acting Capt. Buckland is obviously coming apart, but he also would not have announced Horatio pushed the Captain unless he had evidence to back it up-which would have been Hobbs, who obviously told Buckland that Willard said that Horatio had pushed Sawyer. When Hobbs walked in Sawyer was already dead and Willard dying and asked what he said, "he said I was brave," but then whispered something in Hobbs ear, and you see his expression. From this I would gather he said Horatio did it, so then I assume he told Buckland, he announced it at the trial, but then when Hobbs took the stand said he didn't know. Even if Willet had not told him anything he still could have implicated Horatio. I also have a hard time believing that Willard would have implicated anyone, but it is clear he said something to upset Hobbs.
So after writing all that, I guess it is subject to intrepretation. Maybe the deaths of Sawyer and Willard played on his mind, or maybe Hobbs respected Sawyer's history of courage and did not see that in Buckland and when it came down to it, he would not allign himself with someone opposite of Sawyer at the trial, or felt he would not go against any of his comrades and felt he was now a part of the crew and would not implicate Horatio.
