For much of the past month, a new addition has joined the audioscape of cities across the country: fireworks. Loud ones. Keep-you-up-all-night-ones. And during those sleepless hours in the dark of night, the brain can do some remarkable dot-connecting. One Twitter thread went mega-viral, conjecturing: “My neighbors and I believe that this is part of a coordinated attack on Black and Brown communities by government forces. [...] It’s meant to sound like a war zone because a war zone is what it’s about to become.” That the fireworks were being supplied by the NYPD to cause chaos and provide pretext for a violent police crackdown sounds unlikely. And people reporting out the story have found little evidence to back it up, finding instead that vendors in neighboring states were selling the fireworks in bulk, at a discount, to young people looking to blow off steam. 

But those drawing connections between fireworks and law enforcement should perhaps be given a pass. After all, some of the most outlandish-sounding conspiracy theories in American history have, after a time, proven to be true. For this week's podcast extra, we're revisiting a conversation from last year between Bob and journalist Anna Merlan, author of Republic of Lies, who explained that conjuring up conspiracies is a pastime as old as history.
