Whether it was the attacks carried out in Manchester and London by Islamist extremists or those perpetrated in Charlottesville, Virginia by White supremacists, online radicalisation is the common thread that ties these deadly events together. Ultimately, in the absence of any enforcement, tech companies do not have any incentive to patrol what is being hosted on their sites."
