this article about the involvement of French secret agents and networks who helped to prepare and sustain the killing of 800.000 people in a few months (the best planned genocide ever in history)
http://www.fidh.org/en/africa/rwanda/The-Rwandan-Cases/paul-barril-indicted-for-complicity-in-rwandan-genocide-13567 (this is about Paul Barril and those who follow French special affairs, Paul Barril is really the James Bond, the spider of french special operations but it is probably crazy to expect him to 'open the box of pandora' about all the other special operations he was involved in or has knowledge about under several governments (left or right))
After his military career ended under the administration of François Mitterrand, Barril created the company Epsylon. He allegedly also runs a company called SECRETS (“Société d’Etudes de Conception et de Réalisation d’Equipements Techniques de Sécurité” or “Society for Study, Design and Implementation of Technical Security Equipment”), which currently offers security interventions in foreign countries.
and this information is interesting for those who want more democratic oversight on the private 'security and intelligence (espionage) firms filled with people who used to work for (semi)governmental services. Maybe we should have more limitations on people who cross from the governmental intelligence services into the private apparatus.
Background information about Genocide in Rwanda
the film Rwanda Hotel and shooting guns and some documentaries
you could read - if you have the stomach for it - the book by the Canadian UN general at the time http://www.amazon.com/Shake-Hands-Devil-Failure-Humanity/dp/0786715103
For the first time in the United States comes the tragic and profoundly important story of the legendary Canadian general who "watched as the devil took control of paradise on earth and fed on the blood of the people we were supposed to protect."
I even know some military personnel who were there at the time - and still have the side-effects
If you want to understand why the international community continues to build up its military presence in Central Africa - which it didn't do in Rwanda - than you have to read and see this
Afterwards this distabilized (and still does) the whole heart of Africa (Congo) with as effect that they didn't profit from all the resources but had to wage a war against local militia and Rwandan troops trying to keep those troops as far as possible from their frontier (even if they themselves were in Congo or supporting some militias in Congo). The after effects of the genocide in Rwanda are for that reason thousand times worse than the genocide itself (even if as the general says in his book he only needed a few hundred trained man, some more tanks and fuel).
The trial is important because it is - by accident - now finding proof on paper (how stupid for an ultra secret agent to keep those papers for so long) that in France some networks - with or without official 'silent' support - were helping the regime in place to prepare this genocide.
The name of the operation (genocide) was 'insectcide' (killing people like insects)
The Belgians - one of the best trained UN military forces left Rwanda after ten of their soldiers were deliberately killed (to get them out) - and the role of the Belgian government in this is clearly explained in that book (it took him 6 years before he started writing it)
