I don't care what Mexico would or wouldn't do. Why would you want to emulate anything that country would do anyway? We're better than this to send people "back" to a place they don't have any memory ever of being. These infants and toddlers weren't capable of "breaking the law" when their parents brought them here, and it's the only place they've known. What do you expect them to do? On their 18th birthday, they should say to their parents, "Well, time for me to pack up and go to a strange country where I don't ever remember being and don't speak the language and don't know anyone. Bye, mom and dad?"
