Eighty per cent of women do not report rape or sexual assault to police
So, that’s 80% of society free from the plague.
Ah, that’s not what they mean:
Eighty per cent of women who experience rape or sexual assault are not reporting the crimes to police, research has revealed.
And all through it is “rape or sexual assault” which does rather depend upon which definition of “sexual assault” is being used, doesn’t it?
After all, whatever definition is used three’s a borderline where something could be but turns out not to be. Or even, where some would call it such and others would not.
