attempt to conceal evidence
A cover-up is an attempt, whether successful or not, to conceal evidence of error, incompetence, or other embarrassing information. In a passive cover-up, information is simply not provided; in an active cover-up, deception is used.
- Because we have sought to cover up past evil, though it still persists, we have been powerless to check the new evil of today. Evil unchecked grows, Evil tolerated poisons the whole system.
- Jawaharlal Nehru, The Unity of India: Collected Writings, 1937-1940 (1942), p. 280
