Muslim group say coroner’s decision to include gunman’s social media activity in investigation a ‘landmark moment for the accountability of digital platforms’

The online activities of the Australian white supremacist who opened fire on two New Zealand mosques – and how much of a role social media and internet platforms played in his radicalisation – will form part of a coroner’s inquiry into the deaths of 51 Muslim worshipers in the 2019 Christchurch terrorist attack.

But the presiding coroner, Brigitte Windley, who announced the scope of her inquiry in a decision released on Thursday, has warned of “monumental hurdles” to exploring the terrorist’s online activities – including Brenton Tarrant’s attempts to wipe parts of his digital footprint before committing the attacks.
