PHILADELPHIA -- Joe Paterno and other top Penn State officials hushed up child sex abuse allegations against Jerry Sandusky more than a decade ago for fear of bad publicity, allowing Sandusky to prey on other youngsters, according to a scathing internal report issued Thursday on the scandal.

"Our most saddening and sobering finding is the total disregard for the safety and welfare of Sandusky's child victims by the most senior leaders at Penn State," said Louis Freeh, the former director of the FBI who was hired by university trustees to look into what has become one of sports' biggest scandals. "The most powerful men at Penn State failed to take any steps for 14 years to protect the children who Sandusky victimized."

By lying, Joe Paterno betrayed himself, his legacy, his university and, most of all, the children who were victims of Jerry Sandusky's serial pedophilia, writes Gene Wojciechowski. Story

After an eight-month inquiry, Freeh's firm produced a 267-page report that concluded that Hall of Fame coach Paterno, President Graham Spanier, athletic director Tim Curley and vice president Gary Schultz "failed to protect against a child sexual predator harming children for over a decade."

Freeh called the officials' disregard for child victims "callous and shocking."

"In order to avoid the consequences of bad publicity, the most powerful leaders at the university -- Spanier, Schultz, Paterno and Curley -- repeatedly concealed critical facts relating to Sandusky's child abuse," the report said.

Paterno "was an integral part of this active decision to conceal," Freeh said at a news conference.

Asked directly if Paterno's firing last fall was justified, Freeh answered, "Yes."

Sandusky is awaiting sentencing after being convicted of 45 criminal counts for abusing 10 boys. He faces a minimum of 60 years in prison.
