Well said.
Being a former social worker who dealt with families and sexually abused children for years, what I learned over time is that despite what adults know to be right and wrong - noone ever thinks they will be in the middle of something like this with someone they know. And when/if the day comes - they are rarely prepared to deal with it as well as they might wish or think.
Paterno did notify college authorities, including the Penn State police. What he didnt do was notify the State College police. It really is that simple. There is no indication he tried to hide anything or cover anything up.
Was that "passing the buck" and "burying his head in the sand"? I dont know - maybe. But he was a 75 year old man (at the time) who probably wasnt even sure something like this ever really happened. So he consulted with the people he thought he should - and was told they would take care of it. I read somewhere that he approached McQueary a few weeks later and asked him if he they (the administration) had spoken to him (McQueary) and was he okay with what they (the administration) were doing. McQueary said yes. That says to me Paterno wasn't really sure what was going on - only that McQueary had been really upset and wanted to be sure he felt he was being heard and not "brushed off". My guess is Joe thought, at the time, that he had handled it properly.
But, with all that said, positions of power and influence carry with them certain expectations and responsibilities, including the expectation that you are wiser than the average person and you dont make mistakes. And in this case, Paterno did. None of us will ever really know what he was thinking when he decided how to handle it - but each of us will judge him by our own opinions of what he was thinking.
Ultimately, I think it is sad if this is what he is remembered for. None of us would like our entire lives to be defined by the one big mistake we made - but I think sometimes that is the risk of greatness.
