Why was Saddam's execution Hurried – Interesting points…

Here is an interesting point made by Andaleeb – a fellow commenter on Intentblog – in context of the timing of Saddam’s execution based on the Shi-ite religiouos beliefs:

The only reason I can think behind Saddam’s sudden execution is the international law which is very stringent and it forbids that people over 70 cannot be hanged.Saddam would’ve turned 70 in april.

Secondly,Muharram starts from 21 january and shite observes 70 days of mourning.Maybe its all in the timing..
