“We lose so much if we lose the presumption of innocence. We lose one of the great civilised ideas of the modern era: the idea that no matter how many accusations are made against an individual, he is to be presumed innocent until prosecutors show beyond reasonable doubt that he is guilty. This idea protects all of us, male and female, from destruction by the finger-pointing mob or the powerful state. We ditch this idea at our peril. The new presumption of guilt only benefits powerful, vengeful institutions; it leaves everyone else open to the kind of punishment that ought to have disappeared in the Middle Ages.”
