Around ten in the morning, a Cadillac pulls up to a garage on the North Side Of Chicago. Four guys jump out of the car. Two are dressed in police uniforms. Inside the garage, they find seven men, six of whom are members of a gang led by George Bugs Moran, who runs things on the North Side. Cops come around all the time looking for a bribe, just the cost of doing business. Moran's men do as they're told, hand over their guns, line up against the wall. But then, suddenly, Thompson machine guns appear from under the coats of the cops, and they start firing. 70 rounds later, Moran's men lie slumped on the ground in a pool of their own blood. The shooters get back in the Cadillac and drive away. It turns out, they weren't cops. And when the actual police arrive on the scene, they find one man barely still alive.

This is Joe Thorndike, historian for tax analysts, a nonprofit provider of tax information. And in places like Chicago, this was very evident. Chicago was an ideal place to build a bootlegging empire, a big city centrally located with notoriously corrupt law enforcement. But it was also true in almost every big city. Prohibition didn't start organized crime in the early nineteen hundreds. There was this culture of corruption. So they already had the infrastructure. This is Paul Camacho. He's a retired special agent for the IRS Criminal Investigation Division, and he's on the board of directors at the Mob Museum in Las Vegas.
