You’ve watched too many old movies. You need to move out of the 60’s.
Protecting rape victims from what you describe has been a subject for 35+ years. By the early 80’s most states had
shield laws. Even without shield laws most judges were limiting the scope of cross examination in those days. Victim advocates were part of prosecution teams.
That said there are a lot of questions to ask the alleged victim starting with how a 15 year old ended up at a boozy high school party. Who brought her? Did she drink? How did she get home? I could go on.
I have no doubt that she could pass a lie detector test. Memories change over the decades. I see it regularly as we reminisce with our adult children about childhood memories. We might be discussing an event and my stoker and I look at each other wondering if we were even present.
Oh, and you can stop with that condescending “you are a man” crap. That has nothing to do with anything.
