I can see the insensitivity of the question, nonetheless, IMO the answer to such a question, if differently worded, could yield much information about how physically violent the attacker was, what type of threats were made to coerce her as well as reveal more about her physical and mental state, such as was she drugged by the perp or what.
All facts should come out in a serious matter such as this, no questions should be disqualified.
You think a judge should ask a rape victim why she didn’t keep her legs together?
You think that “could yield much information about how physically violent the attacker was”?
What does that have to do with anything? Are you that moron on tv who thinks maybe it wasn’t really rape rape?
Knees together doesn’t help the slightest if you’re bent over.
