..but it's not really necessary to say ''it's a conspiracy to hide the truth'', Marine and co. are already saying it with abandon. (It's always a conspiracy after all). I will just say on that matter that usually, what people call ''hiding that this is an Islamist attack'' translate to ''wait for 2-3 hours to check who is the culprit and presumably send a forensic team at his home before CNN'' : French media never actually hides the nationality (and religion) of terrorists, and if one french media would, it's rival would not (1)
The idea is that giving coverage and publicity is pretty much what the average Islamist bomber/shooter wants, not unlike serial killers and school shooters. Is this really necessary to publish mugshots of the Nice mad driver, for instance ? (Once again, not for hiding he is a Tunisian)
(1)Contrary to a common ultra-conservative myth, there have been in France (and other countries) for centuries right wing media and left wing media, altough even Rivarol would end up being labelled as ''pinko'' by Internet Tough Guys, but I disgress...AKA, if Marianne (left wing, supporter of the government) tried to hide something, Le Figaro (right wing, politely calling François Holland and Manuel Valls bufoons) would gladly reveal it. The discretion of French media toward certain affairs (mostly the sex life of the poltiical class-hello Mazarine) does not extend to terrorism.
