Sinha maintained good working relations with the secretariat officials and protected police from demoralization because police, having done away with pre-independence legacy no longer symbolised tyranny, domination, intimidation and oppression. He emphasised that in democratic India, policemen symbolised efficiency, service, protection, and help to the people. Caste played no role in promotion, transfer, posting and in working relationship of police officials with ministers or the chief minister in the fifties. S.Q. Rizvi, a retired senior Indian Police Service official, said, "About the qualities of head and heart of this great man, it could be summed up in three words 'Humanism, Integrity and Secularism'. Dr. Shri Krishna Sinha was a great leader and a great idealist endowed with great intellectual attainments. But what to me appeared the most prominent feature was that as a politician he had absolute integrity. A rare quality in a political leader of an area besieged with problems of caste and of low level mental make-up."
