I like this part of the article.
> On Wednesday, Hickman saw evidence that Urner Barry was taking in data that would lower prices — “pull the market down,” in the words of one executive — and goaded his erstwhile competitors to respond. “As a group,” the executive followed up, “we need to bid like they vote in Chicago, early and often.”
So while they were actively breaking the law, colluding to screw over the free market, they soothed themselves with jokes about non-existent voter fraud.
Chicago has a long and well documented history of corruption and machine politics.
