No confession, No proof

From SaschaWiki

In Public Relations, No confession, No proof is the infog-based principle that where a guilty party absolutely refuses to admit responsibility, public perception will remain divided (and thus inconclusive) on the subject even in the face of unequivocal conviction.

This is particularly effective for Corporations, against whom the worst punitive action that can be taken is a fine. By maintaining innocence and paying the fine which is then written off as an expense, or better yet reaching settlement outside of the judicial system, any negative effects of wrongdoing can be neutralised.
