The death penalty seems too little, despite the damned statute of limitations.
There are reasons for statutes of limitations, and among the most important is that the more time goes by, the more physical evidence disappears, circumstantial evidence is forgotten, witnesses can't be located, people's memories fail or filter out what really happened. Or even worse, victims' minds can confabulate, a word which means the brain "automatically," without you knowing it, starts to plug in false information to fill out the narrative. The confabulation often --- often --- involves mis-identifying the assailant.
That is a recipe for a proliferation of unsupportable, or even false, charges.
On the other hand, it *can* take years for victims to recover enough even to tell their stories.
And Hastert is clearly guilty as hell.
So... I don't know.
