Remember that at the moment Sarkozy is battling for something really, really important. Liberty, peace, the rule of Law??
No, however important those issues may be for the peons, they all pale in comparison. We are talking about Sarkozy's political survival. Therefore no holds will be barred.
And since he has been unable to win over Ghadaffi, well then Gbagbo would have to do.
Will Gbago get a fair trial? Very unlikely. This is Africa, you know. Will the French, or the UN, or the rest of the Euroweenies care? No, of course not. It is not as if the US Army or the IDF would have put panties on the head of a terrorist.
