"New Zealand Prime Minister Jacinda Ardern on Sunday said she would be looking for answers from Facebook and other social media firms about how an attack that killed 50 mosque-goers was livestreamed on their platforms. The shootings in New Zealand show how the services tech giants offer can be exploited by extremist groups, said Lucinda Creighton, senior adviser to the Counter Extremism Project. 'Extremists will always look for ways to utilize communications tools to spread hateful ideologies and violence,' she said. 'Platforms can't prevent that, but much more can be done by platforms to prevent such content from gaining a foothold and spreading.'"
