Saying that, people who are employed as youth counselors, especially ones who work with troubled youths all attend training. They are aware of the law and know what is and isn't appropriate and what is and isn't against the law. As youth baseball coach I was required to attend training and had background checks. Sandusky is required to attend these training classes under law. He knows that he shouldn't be naked with children in a shower. In fact he shouldn't be clothed in a shower with children. Any counselor who worked at the Second Mile that was observed doing what Sandusky did would be terminated and the police would have notified.
Sandusky will receive jail time just for those acts. There is also GJ testimony from victims that he had intercourse with the victim.
Sandusky has admitted to one crime. You would have to be a Casey Anthony juror (someone with low intelligence or low reasoning skills) to not believe the victims that testified before the GJ.
Understatement of the eternity
The grand jury’s job is to find things that can be brought before a court, to determine if in the most adverse view to the defendant there would be evidence sufficient to show him guilty. If the alleged intercourse can be brought before the court, let it be. But it sounds like the bearers of the allegations are unexpectedly now squirreling up a tree. This is why there are courts and why matters don’t end with a grand jury (unless it’s a no-bill).
