Why Nirupama Rao should visit Lanka to handle TN fishermen killing instead of calling her counterpart?

This is an eye wash to satisfy Dr.Karunanidhi.Instead, our external affairs Ministry should have called the Sri lankan High Commissioner to his office at Delhi and handed over the letter of strongly worded protest letter to that Government and then to initiate the diplomatic channel effectively.Tamilians problems will not and cannot be solved as Congress and DMK are not sincere and serious.
