In December, 2006, Swift & Co.'s meatpacking plants in various cities were raided by Immigration and Customs Enforcement in what was probably a show raid.

Now, one of their former managers has pleaded guilty (link):

Christopher Lamb is a human resources manager at Swift & Company. He was arrested last summer after authorities recorded him coaching an illegal immigrant on how to use fake documents to get hired... In his plea, Lamb also admitted hiding an illegal immigrant at the plant from June 3rd to June 25th.

The real story will hopefully be this:

He is now expected to give prosecutors even more information about the hiring of undocumented workers at the plant, and his attorney thinks the case will move up the Swift chain of command.
