Syag-
I will preface this with saying that I do not know what happened. However you say
“there was evidence. Children who aren’t abused cannot make up stories and keep them straight under such cross examination”
1) Kids make up stories all the time and if it is a fantasy, they can see it in front of them. Think of kids who have imaginary friends.
2) The point is moot, because the girl is now 18, hardly a child.
3) Your point might have some basis if the story was about something the child would normally have no idea about. This girl apparently was sexually active with a boy friend of whicch there apparently was indisputable evidence. Accordingly this is not stuff that she would have difficulty transferring to someone else.
Just because she said a story is not proof. I do not know if it is true, but proof it is not.
And your argument about what is in the letter being proof about Weberman’s guilt is about the most convoluted attempt at reason I have seen here, and that includes quite a few lulus.
