Back in the United States, hundreds of immigrant workers were detained Tuesday in what immigration officials called a massive crackdown on identity theft. The workers were arrested at Swift and Company meatpacking plants in six different states. Immigration agents entered the plant and separated immigrants from U.S. citizens. The Immigration and Customs Enforcement agency says the workers will be charged with using stolen identities. The United Food and Commercial Workers International Union, which represents workers at five plants, says it will seek an injunction to block prosecution of the detained workers. Union spokesperson Jill Cashen said, “Worksite raids are not an effective form of immigration reform. They terrorize workers and destroy families.”
