Charlie Hebdo's slain editor's book goes on sale "One day, for a laugh, I will have to publish all the threats I received at Charlie Hebdo," French cartoonist Charb wrote in a book he finished just two days before being mowed down by jihadist gunmen. The essay, which went on sale Thursday, states that the fight against racism is being replaced by a struggle against "Islamophobia", which he argues defends Islam more than it does Muslims as citizens who are targeted because of their religion.
