An anonymous poster on 8chan’s "politically incorrect" /pol/ message board, which is known for hosting large quantities of uncensored vulgar and hateful content, announced March 15 that he was going to finally take action and "attack the invaders." He provided a link to his Facebook page where he said he would livestream the attack. While 8chan (and especially the /pol/ message board) is full of pranks, empty threats and hyperbole, this poster was not joking. Shortly after posting the message, he began to livestream a video on Facebook showing him entering a mosque in west Christchurch, New Zealand, and then opening fire on the congregation just as Friday prayers were starting, before driving off to attack worshippers at another mosque across town. Once he was apprehended by the police, the shooter had taken the lives of approximately 49 civilians, wounding scores of others.
