@jr2 : If someone said "I feel like killing myself" and someone else posted "Do it! Do it!", you'd think the person who replied was a heartless, inconsiderate wanker would you not? And if that person did then commit suicide then yes, I would say that response certainly attributed to the act. If memory serves me correctly, the American courts also felt the same way.
The fact is, everybody knew the impact these cartoons would have, riots were already going on because of the movie, whether justified or not, and fuel was deliberately added to the fire. Pleading ignorance to the fact that this would lead to more death is simply a lie.
@ Swantz, we don't need to curtail any values at all, but just because we can draw insulting pictures of a religious character doesn't mean that we must. It's a question as much of self-control as Freedom of Speech, without one, the other will just descend into pure anarchy.
