So let me make some points myself:
1. Publishing the cartoons themselves makes a variety of statements that can't be made by reporting on their existence without showing them.
2. Those statements have great value, independent of any questions of taste.
3. Everything slg says about the difference between publishing a report that a sex tape exists vs publishing the tape itself applies in full to the Mohammed cartoons.
The right to tasteless speech is important and worth defending, but I'm not trying to do that here. I want to counter the argument slg is making, which is that tasteless reporting should be prohibited when you could approximate the same report in better taste. The raw facts always have an inherent value beyond a reporter's interpretation of them.
Or let's use a different example like the Stanford rape case. No one is reporting the name of the victim of that case, but her name is a "raw fact" of the case. Would you support releasing her name and if not, how is that different that releasing the sex tape?
Against someone saying there should be legal liability for releasing it, definitely.
