The New Zealand mosque's attack has been streamed on Facebook, YouTube and Twitter since last Friday. The suspect in the shooting shared photos of his weapons, recorded and livestreamed the killings through a helmet camera. The online platforms claimed they have incessantly deleted the videos, but their efforts have not been enough. It is still possible to find them on the platforms. Facebook announced to have deleted 1.5 million videos on the first day just after the attack. The event raises concerns over the lack of liability of online intermediaries for disseminating harmful content. ?
