"Facebook said it "quickly" removed a live video from the suspected gunman in twin mosque shootings in Christchurch that killed at least 50 people. But the livestream lasting some 17 minutes, according to some reports, was shared repeatedly on YouTube and Twitter, with some footage still being viewed late on Friday. 'There's no excuse for the content from that livestream to be still circulating on social media now,' said Lucinda Creighton, a former government minister in Ireland and an advisor to the Counter Extremism Project, which campaigns to remove violent internet content."
