She is in a developed nation where the legal system is not perfect but i can assure you its a 100 times better then in India. If she really feels she was harassed she should get a lawyer in the US and sue.
Some one made a STUPID COMMENT suggesting that this sort of thing only happens in US. I remember a diplomat and some other high profile rape cases in NEW DELHI not long ago . This is just a verbal harassment case. This can happen in any country on earth so lets stop playing politics and lets try to get to the bottom of the facts as to what really happened. Every one has equal rights in the US regardless of your color, race, religion or profession.
If her claims are real she should persue legal action.
