My friends at Fightingliberals.com [1] are recommending people send their old shoes to the George W. Bush Presidential Library.
In my humble opinion: no no no no no no no no no no no no no no.
Liberals should not make light of or license the physical assault on the leader of a sovereign state, no matter how much he's deservedly hated. This is not how we do politics, unless we're in favor something tending toward anarchy, or fascism.
This seems open and shut to me: the Iraqi journalist should go to jail for a rather long time.
