Such is the complexity and murkiness of sexual relationships in society at large (teenage naked selfies, anyone?) that it is hardly surprising if the criminal justice system sometimes struggles to discover what is true or false. This week saw the rape conviction of footballer Ched Evans referred to the Court of Appeal by the Criminal Cases Review Commission (CCRC). New evidence indicating Evans’s innocence had been presented. He was jailed for five years in 2012 for raping a 19-year-old in a hotel near Rhyl. Another footballer, Clayton McDonald, who had sex with same woman that night, was acquitted.
