The Iraqi who threw the shoe at W says ...

When I threw the shoe in the face of the criminal, George Bush, I wanted to express my rejection of his lies, his occupation of my country, my rejection of his killing my people.

If I have wronged journalism without intention, because of the professional embarrassment I caused the establishment, I apologise. All that I meant to do was express with a living conscience the feelings of a citizen who sees his homeland desecrated every day.
