On March 15, 2019, Australian man Brinton Tarrant live-streamed on Facebook as he committed two mass shootings in mosques in New Zealand.

He was quickly apprehended and unmasked as a passionate white supremacist who'd uploaded a manifesto shortly before the shootings.

thing for him to do. We in Australia started to see him as a lone actor and I think part of that

was just like we didn't really want to have that much to do with it.

It was a convenient narrative.
