Yeah, TV looms large in people's perceptions and expectations of crime and policing. I've heard multiple cops and prosecutors say that juries expect straight-line explanations of motive, when a solid case is much more likely to be based on physical evidence.
In this case I think there's something beyond that. There's an expectation of some kind of Perfect Victim, who will report the crime and submit to questioning and physical examination immediately, remembering details and not being confused despite showing clear, outward signs of emotional trauma. Also one with no criminal record, history of mental illness, erratic behavior after the fact, etc. (TRIGGER WARNING: SJW LANGUAGE) When you're looking for excuses to not believe women about their own experiences, it's a sign of internalized sexism, the same way trying to find reasons that an unarmed black youth deserved to be shot is a sign of racism.
