In Iowa, an estimated 1,000 people gathered in the farm town of Postville on Sunday to protest a May 12th raid on a meatpacking plant. Immigration and Customs Enforcement, known as ICE, arrested 389 workers at Agriprocessors, the largest kosher slaughterhouse and meatpacking plant in the country. It was the largest immigration raid in US history. Nearly 300 workers were sentenced to five months in prison. Attorneys for the workers accused the government of violating due process rights by barring meetings with their clients and ignoring immigration laws.
