Sorry to know that you and your family had to travel back after 24 hours of journey. But just ask a question to yourself ,if you were going to US without Visa, will the officials there in US allow you inside US or at least give you sometime more than what is permitted to produce the the documents. So I dont think it is reasonable to expect Mumbai officials to allow you to get inside India.
Well US officials are lot more strict than the Indian officials I suppose in regards to the perfectness of producing your documents... If you dont have them then that's it.
So friend, I think blaming the indian officials is not fair on your part.
