"Though acts of terrorism take place in the real world, they attain a kind of online afterlife. Materials like those from the recent Christchurch shooting proliferate as supporters upload them to any media platform they can reach. Lawmakers in Europe have had enough, and this year, they hope to enact new legislation that will hold big tech companies like Facebook and Google more accountable for any terrorist-related content they host. 'Whether it was the Nice attacks, whether it was the Bataclan attack in Paris, whether it’s Manchester, [...] they have all had a direct link to online extremist content,' says Lucinda Creighton, a senior adviser at the Counter Extremism Project (CEP), a campaign group that has helped shape the legislation. 'The frustrating thing is that [extremist content] has been flagged with the tech companies, it’s been taken down and it’s reappearing a day or two or a week later,' Creighton says, 'That has to stop and that’s what this legislation targets.'”
