Tech companies put livestream take-down to the test

Major tech companies, international officials and the Prime Minister are in the capital today for a two day workshop to test how fast they can take down a livestream like the Christchurch mosque attack video. After the March 15th shootings, tech giants, including Google and Facebook, designed a protocol setting out what they'd do in such a crisis. RNZ political reporter Charlie Dreaver is at the symposium.
