I have always wondered about people who have the means to get all the way to the Americas from the other side of the world, but have to sneak across the Mexican border. There are legal ways to get to the United States. This family found out the hard way which way they should have gone.
They did what they did to jump the line and get in front of all their other countrymen who ARE in line, doing the paperwork, meeting the requirements and waiting their turn.
