I tought of an interesting paralel between Saruman and Saddam.
after the battle of isengard with the ents, Saruman was in his tower.(and unleashing an army of uruk-hai is a warcrime i guess). They didn't excecute him then...and Saruman escapes to taunt the shire.(read the book fools

)(not that i say saddam would be freed by shunnis)
Sometimes evil must be punished but about death penalty, i got very mixed feelings.
It has the advantage that the person itself is gone as evil but the taking of a life by a state...
Eh... i can just conclude with a "joke" i heard yesterday.
Knock, knock.
Who's there?
Saddam.
Whatya'doing?
Just hanging around.
