Sports doesn't build character. Sports makes characters. If you're a pro athlete you effectively live by a different set of rules. Michael Vick is an excellent example. You think he would've gotten off so lightly if he hadn't been a star athlete.
Vick getting off so lightly, playing for the Eagles, being lauded as someone who has now "seen the light" makes me physically ill. The difference between pro sports, much of college sports, and the Grand Experiment Joe conducted is a gulf miles wide. Joe spent decades building character in his players, something I had the honor of witnessing up close and personally. Even when it meant sacrificing wins, character counted more than football.
if paterno didn't want to get fired he should've gone to the police
That's where you're being misled. Joe wasn't a witness to anything, just McQueary's boss. And Joe did report what McQueary told him to both Schulz and Curley, which is exactly what he should have done and likely what most people would have done in his situation without the benefit of 20/20 hindsight--report what he'd been told to his superiors.
Schulz was senior vice president and the person to whom the campus police reported. But Schulz and Curley did not alert police. They didn't take away Sandusky's keys, which they could have done, since Sandusky had retired in 1999. They did nothing more than tell Sandusky he couldn't bring youngsters on to campus, an unenforceable edict. Then they apparently lied to a Grand Jury.
