Holy crap, now that I watch that protest video back again, it all makes sense. Notice how Mark Karpeles almost walks straight into the protester, stopping perfectly in front of him, mouthing some short words and making basic gestures and then simply strafing around him like a video game character collision. Notice how he maintains the same exact stature and composure. THAT was the ROBOT!! He had us all foxed as well as goxxed.
Watch it again (1:50):
