Emotions are running high in Happy Valley as the ramifications of an ongoing child sex abuse continue to play out. Students have taken to the streets to protest a decision by the university to fire beloved long time football coach Joe Paterno. But some critics are wondering why Penn State students aren't showing more support for the victims of this tragedy.

Penn State seniors Dan Florencio and Davis Shafer explain Ali Velshi how their classmates are feeling about the scandal – and where they're directing their anger.

Many questions remain unanswered in the ongoing Penn State child sex abuse scandal. But perhaps the most important is: Who knew about the alleged abuse of young boys on campus and why did were reports not filed?

ESPN analyst and former MLB player Doug Glanville explains to Alina Cho how this code operates – and how it could have contributed to this tragedy.
