Facebook trained its artificial intelligence systems to detect and block any future attempt to livestream a shooting spree with "police/military body cams footage," and other violent material, in the aftermath of the Christchurch terror attack. The emergency exercise – detailed in corporate papers leaked by whistleblower Frances Haugen – followed the March 2019 mass murder in the New Zealand city, described internally as "a watershed moment" for the Facebook Live video service. 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. "It was clear that Live was a vulnerable surface which can be repurposed by bad actors to cause societal harm," the leaked review stated. "Since this event, we've faced international media pressure and have seen regulatory and legal risks increase on Facebook increase considerably."

Tech start-up Areto Labs noticed online abuse was stopping women from going into politics – so it did something about it. "Imagine you have a job interview and every day, for a month, you have to walk down a dark alley, knowing the worst people in the world are in that alley and they will yell and scream at you," proposes Aucklander Jacqueline Comer, a creative technologist. "If you knew that, you wouldn't apply for the job. And, unfortunately, that's what women in politics have to put up with." Most people in the public eye cop some online criticism, but women get some of the most violent.

In March, a gunman walked into two mosques in Christchurch, New Zealand, opened fire, and killed dozens of worshippers. According to a police official, the suspected gunman was arrested 36 minutes after police were called to the scene. Now, a tech company believes its smart security cameras can prevent attacks like the tragedy in Christchurch, and says it plans to install its AI-powered systems in mosques around the world. Athena Security, the tech company behind the security system, and Al-Ameri International Trading announced the Keep Mosques Safe initiative last week. Al-Ameri International Trading, along with several Islamic non-profit groups, will fund the Keep Mosques Safe effort.
