In the short time I was there, I watched DM as much as possible. He was led in by a guard, straight to the prisoners box. He automatically turned around and the guard (wearing gloves) removed the handcuffs from DMs arms behind his back. The guard stood a few feet from the prisoners box at all times.
DM sat down without looking around much, a straight/neutral face. He had a laptop and rarely looked up from it while the crown or defense were speaking. He did not seem to be looking at the screens as slides were displayed, only typing and looking at the laptop.
He occasionally spoke to Pillay when Pillay approached him, but I could not hear what they said and body language was neutral.
I only saw him glance around the room once and he met my gaze for half a second and I looked down. It was almost easy to forget he was there, off to the side in the prisoners box and looking down to type.
He had an average looking hair cut apart from the braid a couple of inches long behind his right ear. He wore dark jeans, a white dress shirt buttoned to the neck but no tie. A medium gray blazer that was not a slim fit. Large framed, dark plastic style glasses that looked too big for his face. A string around his neck with some sort of small brown pouch/bag on the end. His face looked a lot less puffy than in the mugshot we normally see, and his jaw is more defined.
I wouldn’t say cocky, in the short time I was there, very neutral and looked like a guy just doing work (if I didn’t know he was a monster).
