Publishing the manifesto has created the next mass murderer who knows full well that he can get his manifesto published if he just kill a lot of people.
The media know that, and actively welcome it.
The media will be VERY happy to rush out and cover the next mass murder that they have facilitated.
The failure of the U.S. Justice Dept. to prosecute the New York Slimes for seditiously exposing national secrets in time of war - aside from permitting reckless endangerment of both the Military & public to go unchecked and along with undermining societal confidence in the fair administration of justice & due respect for the rule of law - essentially gave the msm carte blanche when it comes to virtually any further outrageous disclosures.
