Evidence relating to the aftermath of the shooting is suppressed until the inquest begins. When Brenton Tarrant pleaded guilty to all the charges he faced in March 2020, a planned trial was averted and the case against him was never publicly presented.Ĭoroner Windley said lawyers representing the families had decried “the disappointing lack of detail” in briefs filed to her inquiry by the police, arguing they did not allow a proper investigation “of what decisions were made, by whom and on what basis”. Much of the evidence underpinning the inquiry was prepared by New Zealand’s police in 2019 for the criminal case against the terrorist. Some said they were not able to engage expert witnesses or properly instruct their clients as a result. Lawyers for many of the bereaved had urged the coroner to delay the hearings due to the sheer volume of disclosure and delays in receiving, accessing and reviewing it. “However, it is vitally important that this Inquiry is conducted in a manner that retains its integrity and maintains trust and confidence in the process.” “I know this will be an unwelcome delay for many, including those who have long been awaiting the answers and perhaps the closure they hope the Inquest will bring,” coroner Windley wrote. They would be rescheduled for later this year, she said. In what Facebook described as “a major PR win”, the New Zealand prime minister, Jacinda Ardern, used “FB live to update her followers after the announcement”.In a minute issued on Thursday, coroner Brigitte Windley said she had decided “with considerable reluctance” that the hearings would not proceed as planned. The change was announced in tandem with the Christchurch summit held in Paris, aimed at eliminating terrorist content online. The company admitted it had “minimal restrictions in place to prevent risky actors going to live” and in May 2019 announced a “one strike” policy that blocked accounts with a single terror violation from using Live for 30 days. The Christchurch video now scored 0.96 on the internal graphic violence scale, well above the intervention threshold.Įlsewhere, this set of leaked documents show how keen Facebook was to repair its damaged image. It also included first person shooter video game footage, as examples of content not to block.Īs a result of this and other efforts, the documents show that Facebook believed it had slashed the detection time from five minutes to 12 seconds. “The training dataset includes videos like police/military body cams footage, recreational shooting and simulations,” the internal material says, plus “videos from the military” obtained from by the company’s law enforcement outreach team. A key element was to retrain its company’s AI video detection systems by feeding it a dataset of harmful content, to work out what to highlight and block. It also details how Facebook grappled with the problem, trying to improve its cutting edge technology. The leaked documents, initially published by Gizmodo, underscore the failure, showing that at the time of Christchurch, the social media giant was “only able to detect violations five mins into a broadcast” – and that the attack video only scored 0.11 on an internal graphic violence scale when the threshold for intervention was 0.65. No Facebook user complained for 29 minutes and executives were forced to admit its detection systems were “not perfect”. “Since this event, we’ve faced international media pressure and have seen regulatory and legal risks increase on Facebook increase considerably.”Īt the time Facebook admitted its AI systems had failed to prevent the broadcast, and the video was only removed after the company was alerted by New Zealand police. “It was clear that Live was a vulnerable surface which can be repurposed by bad actors to cause societal harm,” the leaked review stated. 1.5m uploads had to be removed in the 24 hours afterwards. The white supremacist attacker was able to broadcast a 17-minute live stream of the attack on two mosques that was not detected by the company’s systems, allowing it to be swiftly replicated online.
