In the aftermath of the mass shootings many questions are being asked about how the attacks could happen: of intelligence agencies, of our gun laws and of the tech giants who allow harmful material to be conveyed to millions of users. In 2015, Andy Parker's daughter Alison, who was a Virginia based TV reporter, was fatally shot by an ex-employee of the station during a live interview. The gunman later posted a video of the shooting to his Twitter and Facebook accounts. Four years later, that video is still available online on google owned platforms. Andy Parker has been campaigning tirelessly on two fronts - firstly, for gun law reform, and secondly against tech platforms for failing to block and take down objectionable content.
