In an open letter published by the New Zealand Herald, Facebook COO Sheryl Sandberg finally addressed the shocking mass shootings that left 50 dead at two Christchurch mosques. The first of part of the deadliest mass shooting in modern new Zealand history was live-streamed on Facebook by the attacker.

But while the site’s technology was used the broadcast the horrific attacks, Facebook has largely stayed silent on the matter in the intervening two weeks. Sandberg broke that silence in her letter, which addressed grieving families and a shaken nation. The note addresses aspects that the site could have handled better, but the company still appears to be at something of a loss for how to handle such an event.
