I don't think people come out and taunt rape victims openly be it in a village or a big city like Delhi.
They may say things in private like the victim must have done something to provoke this kind of behaviour from the man who did this to her.
The rape vitim's identity is not revealed to the public.The cases may make news but the name and the picture never are made public.In case of Sanchi also people may have heard about the case.But they don't know whether it is Sanchi or not for sure.
The trial is conducted behind closed doors only the family of the man accused of rape and the family of the victim are allowed inside to protect the victime from being identified.
So it is quite natural that Udaipur public did not know that it was Sanchi who was the victim.
But now that the family has started to think about marriage and because of Sanchi's condition that it should be revealed to the family of the boy before hand it the news about Sanchi may spread.
