The attacks targeting people praying at the mosques a year ago shocked the nation and prompted new laws banning the deadliest types of semi-automatic weapons. It also prompted global changes to social media protocols after the gunman livestreamed his attack on Facebook, where it was viewed by hundreds of thousands of people.
The sudden turn in the case took survivors and relatives by surprise, and brought relief to people across New Zealand. Many had feared Australian white supremacist Brenton Harrison Tarrant would try to use his trial as a platform to promote his views. He'd outlined those views in a 74-page manifesto he published online shortly before the attacks.
