Re: Nobel peace prize winner to face ICC
Liberian President, Samuel Doe was the first world leader to be tortured on camera before being executed and his body desecrated on September 9, 1990. note -september 
On the other side, Doe sits on the floor begging for his life. The camera oscillates between the two scenes. At some point, the rebels hold him back as one of them cuts off his ears. He does it almost casually, and when Doe is allowed to sit up again, he is earless and bleeding onto his naked body. They also cut off his fingers and toes.
