I don't normally approve of the death penalty but his fate ought to have mirrowed that of Romania's Nicolae Ceaucescu, who was dealt with swiftly and effectively
He did get a trial though. One quite similar to this one. Hence the point of it being a kangaroo court. Of course both were obviously guilty anyway, but it would've been more appropiate to deal with them in a more legitimate manner.
What is more legitimate than a trial infront of your peers? It's being televised around the world, and he is receiving both domestic and foreign council. Any sign of a kangaroo court will be seen before millions of people, but I doubt that will happen since there is so much evidence against him. He's getting a fair shake, unlike what he did with so many of his citizens over the years.
