How student survivors of the Florida school shooting are using social media to demand change

“As teenagers, we know how to use social media and we know how to take advantage of it.”

Before 14 February 2018, Delaney Tarr used Twitter to share pictures of dogs, screenshots from her favourite Netflix shows and drawings by artists she admired. After a gunman murdered 14 of her classmates and three of her teachers at a high school in Parkland, Florida, the 17-year-old’s online presence changed. Since then, her Twitter profile has been made up of moving tributes to her dead classmates, strongly worded arguments with Fox News presenters, and a hashtag: #NeverAgain.

“When the tragedy happened, we realised that this was how we were going to reach as many people as possible,” Tarr told me when we spoke on the phone.
