Raymondville, UNITED STATES: Female detainees walk to the exercise yard inside Homeland Security's Willacy Detention Center, a facility with 10 giant tents that can house up to 2000 detained illegal immigrants, 10 May 2007 in Raymondville, Texas. The 65 million USD facility was constructed as part of the Secure Border Initative last July and now where many of the former "catch and release" illegals are detained for processing.
