Sure, and if there was a denial then I'd be inclined to believe that, but as far as I know there hasn't been one. Even his many supporters are crying out for him to be treated well in prison, I don't think there have been any of his supporters claiming his innocence?

In the US system, the defendant is given the presumption of innocence and isn't obligated to issue public denials and such. So regardless of whether or not he did it, he's probably better off just not saying anything at all.
The fact that he's active-duty military changes a lot of things about the process too, but apparently not in the direction of making it into a public media trial.
