In Waterloo, Iowa, hundreds of people marched on Sunday to protest last week’s immigration raid at the Agriprocessers kosher meatpacking plant. Immigration agents detained nearly 400 immigrant workers in what has been described as the largest single immigration raid in US history. The raid resulted in more than ten percent of the town of Postville, Iowa being locked up. On the day after the raid, half of the school system’s 600 students were absent, including 90 percent of Latino children, because their parents were arrested or in hiding. Many of the workers have been held at a fairgrounds usually used for exhibiting cattle. No charges have been filed against the owners of the meatpacking plant, Agriprocessors.
