The camera is too shaky to tell and I don’t feel like watching it again. There is a lot of movment and shouting but you can see Qaddafi’s physical condition grow worse from one second to the next. Obviously from kicks, punches, and possibly stab wounds. He is bleeding pretty heavily by the end of the video and is basically being held upright by his captors.
These still frames show one of the rebels sodomizing the dictator with a knife or trench tool.
