Undocumented Harvard Student Not Deported

Information here. Is there any irony to be had in the near-universal public indignation about a different kind of "undocumented" Harvard student being thrown out of the university? ("String him up! Oh, he's an illegal immigrant, not an illegal applicant? Well, um, I guess that's different then.") Forgive the condescension but it's indicated where questions are studiously avoided by those of us who don't like to question our assumptions.

Here's one angle: is there a moral difference between those two situations? Furthermore, is the U.S. right to selectively keep an undocumented (foreign national) Harvard student but not a 52-year-old landscaper? (Answer: yes.)
