There is no case to answer because Ms Diallo is an 'unreliable witness'. No medical or forensic evidence is relevant. When raped women are 'witnesses' in the legal system, their credibility is the topic of contention, not the evidence. The issue of consent is largely ignored. Criminal law requires 'presumption of innocence' and 'beyond reasonable doubt'. Is it this combination that results in an inadequate legal response to sexual violence or other factors? Can this be changed?
