No one with back problems would turn to wave like that. No way.
I'll betcha that he's thinking "oh, geesh..WHAT DID I JUST DO?!" (with the wave).
Probably a subconscious, automatic reaction. Let's hope the judge hears about it and tosses his rear in jail.
That's what I said...to the television. LOL When I saw him turn to the left, then to the right and wave, I couldn't believe it. Hope the judge sees that too. I do believe it's in distress, but not from extreme back pain, but distress over the situation he has created for himself.
