Paterno's conducting their own investigation is just kind of pathetic. Its not like anyone will trust their results over the findings of Freeh. And they look like real assholes after begging people to wait for the facts before reaching a judgement, then when they decided they didn't like the facts they decided to call them opinions and conduct their own investigation.
I really think they'd be better served with the "No one is perfect, Joe made mistakes but also did great things. Were sorry to the victims, their families, and the university." instead they throw a hissy fit and remain in denial.
