Mickey Kaus made a great point about building a wall across the border. It's compassionate, and enforces laws going in to the future. Let the illegals already here stay here and come in from the cold, and build a wall. It's a grandfather clause. If you're already here, great, if not, too damn bad, you ain't coming unless you do it the legal way. Makes sense to me, and avoids the trials and tribulations that would come with deporting millions of illegals already here.
