It's been five years since a gunman walked into Sandy Hook Elementary School and killed 20 children, six adults, and himself. To mark the tragedy's anniversary, CNN anchor Jake Tapper in 2015 memorialized the victims on Twitter, posting the names and pictures of those killed on December 14, 2012:
The tweets are heartbreaking, but they also offer a reminder that Sandy Hook was supposed to be the mass shooting so horrifying that it finally convinced America to do something about its extraordinary levels of gun violence. Yet even though the research has pretty definitively linked America's easy access to guns and abundance of firearms to more gun violence, nothing was done on the federal level. And since Sandy Hook, there have been more than 1,500 shootings in which four or more people were injured or killed.
