Normblog makes the point that it is pathetic to go around needlessly offending people just for the sake of it, but these cartoons were not intended to offend and are quite innocuous. They are also not that good or that funny, but offensive? Those Muslims that are being threatening about this are not only being idiotic, they are being hypocritical. Middle Eastern media has regularly caricatured other religions and even depicted Muhammad in the past. They are also missing the point, that if they really want to limit the number of people that see these things, you ignore them, not go trying to suppress them.
Only the BBC has so far raised its head above the parapet. If the reason not to publish is that it will cause unnecessary offence then fair enough, but the reasons I see for the UK media reluctance are cowardice, and that is never a good reason.
Publish and be damned, you have a duty to free speech now, just to show you are not intimidated by these religious idiots.
