In a Politico article from 2009 - the reporter attended dinner at Podesta's - Podesta tells of slaughtering pigs during his college days.

This isn't direct evidence of anything, but is still useful to know about Podesta and keep in mind as more substantial evidence is considered, IMO. For one thing, consider the callousness Podesta seems to show. He seems to credit his brother for the painting on the wall of his office of men about to eat another man, but this article shows that he seems to think that way as well.

From Politico:

"Talk of pig roasting and slaughter kept popping up during dinner and was the last tale Podesta told before the guests left. To earn money while attending law school at Georgetown, he spent two years working at Turkey Run Farm in McLean, now called the Claude Moore Colonial Farm, an 18th-century re-creation."

"Standing in the kitchen and acting out his role, Podesta explained: “It’s best to do the butchering at 4 a.m., “because pigs should be slaughtered when it is cool, and it takes a long time to roast them. The pig is hauled on a front-end loader in order to split and gut it. It’s most important to slow the pig down by shooting it between the eyes so you can cut its throat. It makes the pig less ornery and a whole lot more cooperative than if you just stick a knife in its throat.”

"In homage to these skills, Podesta used to have a picture of a pig on a spit as his screen saver, but his staffers made him get rid of it, because he said: “They couldn’t stand looking into the pig’s eyes during meetings.”
