Postville, IA – More than a thousand people gathered in the small town of Postville, Iowa, July 27, to protest the largest immigration raid in U.S. history – the raid took place here at the Agriprocessor kosher meat processing plant – and to demand an end to such immigration raids. On May 12, about 400 immigrant workers, mostly from Guatemala and Mexico, who worked at the plant were detained by Immigration and Customs Enforcement (ICE) officials. Most were either put in jail or deported.
