It does seem like George is in more trouble since the Trayvon assault. I wonder if he has changed neurologically, and hence emotionally, due to having his head bashed on the ground a few times. It's not a question I've seen raised.
If not the head bashing itself, the trial and non-stop threats and character assaults by the local lynch mobs, communities perpetually “organized” against him, and of course the lies out of the drive bys in the media would have left him with PTSD.
