He most certainly did help cover up the entire scandal. And, since you don't know anything about Penn State or Joe Paterno then I will fill you in. He is in charge there, what he says goes, he is a god there. When the Athletic Director talked to him five or six years ago about retiring (because Penn State had been bad for a while) he basically said no and told him he would coach until he decided not to. He told HIS BOSS basically to blow him! All Joe Paterno had to do after any of the three main incidents was tell the police. Yet he refused to. He ignored it. Ignored child rape. Touching a child is bad enough. Sandusky was, by the grand jury indictment accusations, repeatedly raping children. Yet, Paterno continued to turn his head as Sandusky was allowed Emeritus status and given keys to do whatever he wanted at the university. That must have been a little odd, eh? Walking down the hall and seeing Sandusky coming the other way> "Hey coach, good morning." "Uh, hi?" Awkward...
Of all the people there on campus, he had the ability to stop it immediately; instead he let a criminal walk around freely to continue to do what he wanted to more children and to get away with it.
So, yeah, that does make him a bad person. If it doesn't then what do you think does make someone a bad person?
