The rise of fake news

In December 2016 Edgar M. Welch drove six hours from his home to Washington DC, where he opened fire in a pizzeria with an assault rifle. He had previously read an online news story about the restaurant being the headquarters of a group of child abusers run by Hillary Clinton. He decided to investigate for himself; fortunately, no one was hurt.

• He had become concerned after reading an untrue news story.
