A couple thoughts on this as I agree I hope the lessons of Clemente et al are someday learned.
First, wasn't one of Clemente's main points that we shouldnt use hindsight to say that everyone made aware of allegations against a "nice guy predator" are guilty of covering up? The whole point is that they have fooled the entire community. So we shouldn't presume nefarious intent upon everyone who heard something about the guy, because there's a reason they didn't take it seriously. Yet, with Michigan State, we Penn Staters have seemed more than happy to apply the same "cover up" nonsense that was thrust on Joe etc to MSU admin. How is that furthering the Clemente point? That's just perpetuating the status quo, that these things are obvious and anyone who didn't report immediately was just covering up. The lesson being taught should be that you have to take every accusation seriously, because you'll be fooled by these "nice guys." Instead, the current MSU narrative is the same as PSU, that they knew and intentionally covered up. That doesn't help advance Clemente's point IMO.
Second, there are victims who said Nassar abused them even while their parents were in the room. How this could occur is beyond me, but apparently the 2 adults rule wouldn't even prevent all situations. It's an extraordinarily frightful thought that it could be happening in front of you and you don't even know.
