Three months after the largest immigration raid in US history, when nearly 400 workers were arrested at a meatpacking plant, Postville, Iowa is a changed town. Postville lost more than a quarter of its population in the raid. And for those left behind, namely the wives and children of the men taken away, the town has been turned into what some have described as an open-air prison. Dozens of immigrant women remain in Postville without status or a means of support. Many of them are even forbidden from leaving and have been made to wear electronic monitoring bracelets.
