WOFF BLITZER: So if people want to come from Guatemala or Honduras or El Salvador or Nicaragua, they want to just come into Mexico, they can just walk in?
CALDERON: No. They need to fulfill a form. They need to establish their right name. We analyze if they have not a criminal precedent. And they coming into Mexico. Actually...
BLITZER: Do Mexican police go around asking for papers of people they suspect are illegal immigrants?
CALDERON: Of course. Of course, in the border, we are asking the people, who are you?
And if they explain...
BLITZER: At the border, I understand, when they come in.
CALDERON: Yes.
BLITZER: But once they're in...
CALDERON: But not -- but not in -- if -- once they are inside the -- inside the country, what the Mexican police do is, of course, enforce the law. But by any means, immigration is a crime anymore in Mexico.
BLITZER: Immigration is not a crime, you're saying?
CALDERON: It's not a crime.
BLITZER: So in other words, if somebody sneaks in from Nicaragua or some other country in Central America, through the southern border of Mexico, they wind up in Mexico, they can go get a job...
CALDERON: No, no.
BLITZER: They can work.
CALDERON: If -- if somebody do that without permission, we send back -- we send back them.
BLITZER: You find them and you send them back?
CALDERON: Yes.
When they go rogue (off teleprompter) we see behind their masks.
