I think this is Arbour attempting to create some sort of doubt. I'm not sure why they won't play that interview though. Who knows what kind of crazy stuff JB may have said. He could've said he and NH had been involved(more than platonically) at some point in the past or that NH knew what he was going to do? I do wish we knew, but to me it still doesn't make me doubt that the attack was premeditated.
