U.S.C. sex and drugs scandal: would attending such a graduate school hurt one's chances at an academic career?
One cannot, of course, guarantee that there will be no negative outcomes for going to a school currently being rocked by a scandal. But I cannot imagine they'd have significant repercussions outside the occasional comment about "What was that like?" Especially given the current scandal appears primarily focused on a Dean (a position fairly far removed from the average graduate student) and his colorful private life.

If that scandal had major repercussions in terms of academic fraud, human subjects protections, or specifically involved the lab you were in, the answer might be different.
