Anderson Cooper In Disbelief Over Penn State Allegations (VIDEO)

On Thursday night, Anderson Cooper questioned how so many people could know about the child sex abuse allegations against former Penn State defensive coordinator Jerry Sandusky and do almost nothing about them.

The campus erupted in scandal earlier this month when Sandusky was charged with sexually abusing young boys during and after his tenure at Penn State. Other college officials have also been charged with perjury for failing to report the allegations to the police, and coach Joe Paterno was fired.

Cooper found it unbelievable that the local and university police, the local district attorney and Pennsylvania child welfare failed to take action after one of the potential victim's mothers alerted them to the alleged abuse. "Essentially, nothing happens," he said, summarizing their response.

Cooper wondered whether officials outside of Penn State knew about Sandusky's alleged transgressions, and also questioned Coach Paterno's claim that he was first alerted of the allegations in 2002. "If so, how could it be that Joe Paterno, his boss, mentor and close friend, did not know back in 1998 what was going on?" Cooper wanted to know.
