This tweet from Edwy Plenel really exists. On January 17, 2015, ten days after the Charlie Hebdo massacre, Edwy Plenel wrote: "The miserable childhood of the Kouachi brothers. Must read to regain composure." Here is who this man is: the one who, in the face of murdered journalists, first seeks the social excuse of the assassins. #EdwyPlenel #CharlieHebdo #LibertéDexpression (translated)
