[CW details on real and fake pedophilia cases]

In 2016, three decades after the McMartin trial, WikiLeaks, in cahoots with Russian hackers, published the private emails of top Hillary Clinton adviser John Podesta. In one, Podesta is invited to a fundraiser at Comet Ping Pong. Amateur internet sleuths blew it up into a conspiracy theory about a child-sex ring. The pedophiles communicated in code: “hotdog” meant “young boy”; “cheese” meant “little girl”; “sauce” meant “orgy.” The theory was easily debunked. Eventually it was abandoned by the high-­profile internet figures who’d initially given it oxygen, but not before Pizzagate, as it was immediately dubbed, had spilled over into reality. In December 2016, a 28-year-old man named Edgar Maddison Welch, having driven from North Carolina to Washington, DC, fired an assault rifle inside Comet in a bid to rescue the children he thought were locked away there. No one was hurt. Welch was sentenced to four years in prison.
