PM Modi in his message to Congress in Rajya Sabha says, "Threats don't work in a democracy". He further said that he used to get threatening letters continuously for 14 years in Gujarat to send him to jail. He said he was aware of the tricks the opponents played on him but he didn't want to reveal. But sometime or the other it will be recorded in the Indian History. He said that everybody know who has the history of threatening s and the language.
