Actually, it had everything to do with it.
Via Telegraph:
Speaking earlier, Nicolas Sarkozy said he would try to legislate against anyone who visits websites glorifying terrorism. Le Monde is reporting that would probably run contrary to the French constitution. We’re expecting the president to begin addressing a rally of his supporters in the next few minutes
Locals – the majority of them immigrants of North African descent – said he started out as a kid who loved football and motorbikes. But he gradually became “indoctrinated” by Salafist extremists, who turned him into a “predator”, in the words of a community leader. Merah and his brother also had links to two extremist groups, it seems.
President Nicolas Sarkozy warned that those who visit extemist websites will be severely punished:
France has shown its indignation and grit but has not allowed anger to take over.
The Muslim faith has nothing to do with the insane acts of this man. Before targeting Jewish children, he targeted other Muslims.
We must be implacable in defending our values. We will not allow this ideology to affect us.
From now on, any person who habitually consults websites that advocate terrorism or that call for hatred and violence will be punished by the law.
France will not tolerate forced recruitment or ideological indoctrination on its soil.
