This week, at a refurbished camp for oil and gas workers, the Department of Homeland Security officially opened a new detention center for women and children who cross the southern U.S. border. In DHS director Jeh Johnson’s view, this is a move to prevent people from crossing the border at all. He wants to stem the tide of “illegal migration,” and he believes that detention is one means to do so. “Frankly, we want to send a message that our border is not open to illegal migration, and if you come here, you should not expect to simply be released,” said Johnson. Let’s look at the positive side for a moment.
