And one year ago today, federal immigration agents raided a kosher slaughterhouse in Postville, Iowa, arresting nearly 400 immigrant workers in what at the time was the largest immigration raid in US history. The raid devastated the town of Postville. The slaughterhouse owned by Agriprocessors has since closed down, taking with it hundreds of jobs. The number of vacant rental homes in Postville has soared. Half of the town’s population has left. The town’s mayor resigned earlier this year. Nearly all of the male workers arrested last year were deported. Many of the female workers have been allowed to stay to care for their children but are unable legally to work.
