What exactly was there for Univeristy Police to investigate? They investigate by interviewing MM and JS immediately, obtain from Jerry the victim's name, interview him and his parents. This is what Harmon has testified he would have done immediately, given what he knew of 1998, if Schultz had told him anything about what MM had seen. Possibly, it's why Schultz told him nothing, as harmon has testified.
In 1998, there was a complaint...from a victim. They had a name.
In 2001, McQueary witnesses something...and did nothing. What were the UP supposed to do? Interview McQueary and Sandusky? What does that accomplish? As I just said, that is how an investigation works. Sandusky gives them a name, immediately. If he refuses, now he's admitting guilt. Backtracking the kid's ID through TSM of who jerry was with the night before would have taken minutes. There was no victim identified...no complaint lodged against Sandusky...so the only way to find THAT out was to go to The Second Mile.
Its kinda like telling the police you witnessed a hit-and-run. No it's not anything like a hit and run. This is a poor analogy for several reasons. In a hit and run, you always have a victim and and sometimes, a description of the car. There are far better analogies available. You saw the driver, but you fled the scene before getting any details. Police investigate, find no victim at the scene, nobody checked into a hospital, no damage to the car...so now its a game of he-said, he-said. Can the police file charges without any evidence besides the eye-witness' claim that he saw a hit-and-run and the driver but that's it? What are the cops going to do with nothing more than the testimony of a single person and no other evidence?
