In a letter dated October 1, 2010, a copy of which is with Sikh Siyasat Network, he had opposed the plea for rejecting the human bomb theory put forward by defense lawyers, appointed by other persons sentenced by the Sessions court. Balwant Singh says that he himself tied the bomb belt to Bhai Dilawar Singh to eliminate Beant Singh. He rejects the contention of prosecuting agency, CBI, that Dilawar Singh was motivated and inspired by someone else to become human bomb. He adds that it was the nationalist feelings of Bhai Dilawar Singh; the cries of mother land Punjab, which was unable to bear innocent killings any more, and atrocities committed by Indian State on Sikhs, which motivated Bhai Dilawar Singh to take that step. He says that CBI wanted to defame their struggle by contending that they wanted to kill maximum number of persons through that bomb blast. He said that they were against innocent killings but wanted to kill Beant Singh, who was the kingpin behind mass level human rights violations, enforced disappearances and extra-judicial killings in Punjab.
In this letter Bhai Rajoana has severely criticized CBI for its dual standards. He says that CBI sees culprits of Sikh Genocide 1984 as great patriots but term Sikhs, who followed the path shown by history to suppress the evil, as terrorists.
Bhai Balwant Singh Rajoana has reaffirmed his faith in establishing Khalistan, independent sovereign state for Sikhs. He has refused to bow before imperialist and barbaric Indian State to save his life but demands freedom for his people.
