An important example is the terrorist attack on Christchurch of March 15,
2019. Video footage of the attack was livestreamed on Facebook and spread
virally to several other websites. Facebook ultimately issued two public
announcements describing their efforts to remove this graphic footage. They
provide detailed timelines of events, starting with the ﬁrst livestream, as well as
data on how often it was subsequently viewed, shared, re-uploaded, and
ultimately removed.32 In its response to the Christchurch incident, Facebook
also took the unprecedented step of inviting a legal academic, Kate Klonick, to
sit with response teams. Klonick later published her observations (Klonick
2019).
