A Washington, D.C. pizzeria was the center of online attacks on fake news websites saying that it was the center of a child porn ring. The owner was harassed online and received death threats. The New York Times reported it shortly after the 2016 presidential election.
Two weeks later, a man who apparently believed what people shared on Facebook and Twitter about it fired shots at the restaurant.
The articles making those allegations were widespread across the web, appearing on sites including Facebook and Twitter. Apparently concerned, Mr. Welch drove about six hours on Sunday from his home to Comet Ping Pong to see the situation for himself, according to court documents. Not long after arriving at the pizzeria, the police said, he fired from an assault-like AR-15 rifle.
Fortunately, no one was hurt. The man was arrested.
