In Iowa, 270 undocumented workers have been sentenced to five months in prison. The workers were arrested earlier this month in an immigration raid on a meatpacking plant. It was described as the largest single immigration raid in US history. More than ten percent of the town of Postville, Iowa were put behind bars. Attorneys for the workers accused the government of violating due process rights by barring meetings with their clients and ignoring immigration laws. The hearings took place at a fairgrounds usually used for exhibiting cattle where the workers were held. Only a small number of the workers were found to have criminal records. No charges have been filed against the owners of the meatpacking plant, Agriprocessors.
