education.
the judiciary need to be educated and need to take a strong role in educating juries about rape myths. we need to destroy the ideas that loads of women regularly lie when they regret having had sex, that rape is always a violent physical attack that leaves injuries, that it is only rape if it is overcoming active physical and verbal resistance.
They also need to discuss victim behavior, someone disassociating will be perceived as lying because they are too unemotional, while someone who shows too much emotion, or the wrong emotions after repeated bullying assertions that they are a liar will often be assumed to be someone who has been 'caught out'. trauma can also do odd things to memory. sometimes, parts of the incident will be forgotten until something triggers recall of that. This is all normal, commonplace, but all results in the witness being considered unreliable. these and the above need to be talked about to juries as a prelude to more education in society about consent and rape myths.
Questioning also needs to be limited. There need to be clear guidelines on where a victim's medical history is deemed relevant. These are supposed to be in place, but in reality, the defense can still go on a fishing expedition to try to provoke the victim and can drag up any mental health history and use public prejudice, not actual fact to discredit them. people already think women lie loads. and loads of women are crazy. put the two together and you've got no hope. there's also a line between providing a defence, and open bullying. these require guidelines to judges about when evidence should and shouldn't be admissible and when to halt questioning.
and judges who encourage rape myths instead of challenging them and who allow fishing expeditions and bullying of witnesses need to be kicked off the bench.
and yes. additional support to victims, someone who can act as a buffer between them and the judicial process. whose voice will be listened to if the police inappropriately question victims, or try to shuffle cases away because of their own prejudices. who can explain the court process, introduce the victim to the prosecutor and give them an idea of what will be required of them.
