In September 2005 a Danish paper called the Jyllands-Posten
("Jutland Post") did an article on Islam and political correctness.
They invited 12 cartoonists to draw a depiction of the Prophet
Muhammad.
One of the cartoonists evaded the question by drawing a
schoolboy called Muhammad. The others depicted the Islamic prophet
with varying degrees of offensiveness. Depictions of the prophet
are not only forbidden in Sunni Islam (it's considered a form of
idolatry), but also considered offensive. In Shi'a Islam they are
generally tolerated. However, they too were offended by the content
of the cartoons, especially one which depicted Muhammad with a bomb
in his turban.
