Saddam was not executed by Iraq, but they did pretend to execute a look alike, who was allowed to speak at his trial, in character, but whose voice was not transmitted.
This may just be a poor look alike as dictators do tend to be victims of assassinations. It would be normal practice to distribute false information about his appearance. Both pictures may be false!
Osama Bin Laden is another whose appearance has altered much. Skulduggery from Skull and Bones?
Shurely not! Mine’s a triple Brandy!
