I don't think anybody could find them. Nobody even knows how many there are. But if they come for welfare benefits and you know they're illegal, (you should) deny them the benefits. If they commit a crime, send them home. Today in many cities, you're not even allowed to ask them their immigrant status. Policemen tell me they can't ask that question to find out if they're illegal. It's politically incorrect to ask a person his immigrant status because that would (be like saying), "If you've broken the law, maybe you ought to go home."
How do you see immigration in the future?
If we have a healthy economy, we would probably have a lot of people coming back and forth working in this country. There was a time when (immigrants did that). That was when they didn't expect to get easy amnesty.
