There has been a lot of justified criticism of the police, support, medical and legal aspects in the thread. I'd like to add one in relation to jurors - group polarization. There are academic studies on this, and a given case may be different.
Specially, on one side you'll find a larger portion group that think the assault is incredibly serious, they have high levels of empathy. With that perspective they'll be very concerned about the victim, but also very much so about any potential for wrongful conviction.
On the other side you'll find a surprising number of people who believe in what are called those awful "rape myths" (drinking, they were friends, I've had bad sex too, it's was only 5 minutes get over it, etc.). Sadly this is not just men too.
Polarized juries make it so much harder to get a conviction. In contrast, everyone believes armed robbery is bad, stealing a car is not acceptable, defrauding customers, selling Class A drugs has to be stopped, etc.
