Not quite sure whether it was a good thing or a bad thing hanging Saddam, he did keep his country a bit more in check that the 'coalition forces'...
Anyway, for those that wish to see what looks like his actual hanging from someone's phone camera, this video is on Google Video.
It does actually show Saddam falling through the trap with the noose around his neck so beware.

I didn't really notice this at the time, but the 'official' footage differs a little from this phone camera footage, in the fact that Saddam is being shouted at with jibes to 'go to hell' and he retaliates - far from the 'dignified' portrayal in the official video release.
More details can be found on this BBC news article about the differences with translations.
