Chertoff is right about this, unfortunately. He is part of the problem, but as a career civil servant, he's well aware that every facet of America's power structure is basically against doing anything about immigration. How can deportation happen when it's opposed by big business, urban political machines, ethnic lobbies, BoBo liberals, the judiciary, the press, academia, organized religion, and the civil service and various state organs such as schools from medium-sized towns up to the Federal level. They won't comply, and there's no one to make them comply. Sure, congress can pass a law, but it will be opposed by lobbyists, called racist, denounced in the press, attacked from the pulpit, undermined in the schools, blocked in the courts, and be dilatorily enforced, if at all, by the people tasked with enforcing it. And as soon as our attention is directed elsewhere, someone from ADM or Tyson will call a well-placed Senator and ask him to take off some of the heat his workers are suffering from la Migra.
