states are better at hiding & denying crime
-Cohen - spiral of state denial:
stage 1: 'it didn't happen'
stage 2: 'if it did happen it is not what you think'
stage 3: justification of the act
-Matza & Sykes - neutralisation theory
justification of the act through denial of harm; denial of the victims; denial of responsibilities; condemning the condemners & appeal to higher loyalty
