It's always the same points that come up, time and time again.
The problem with rape, and more so now than in the past with the advent of DNA, proving sex did, or sometimes didn't take place is reasonably easy. Proving or disproving consent really is tough.
She says she didn't. He says she did. Who do you believe?
In other words, rape isn't like mr x hit mr y with a bat in front of 200 witnesses and walked off muttering "I'm glad I did that!".
It isn't clear cut and I'd suspect there's a lot of rape convictions as well as aquittals which are very unjust.
So, yes, both sides should not be named.
The counter argument is the same as Kestrals for naming the victim, if you name them, others may come forward to say the same thing happened with that person to them.
It's a balance, that is impossible to get right.
None of this applies so much in DLT's case. the offences are too long ago, and there is no DNA or other forensic evidence. Well, unless someone filmed it. So it is just one word against another, and nothing supporting either side. Is that not a bit dodgy? Yes it is on the face of it, but I've not seen the evidence.
As for the 15 year old, again, there's no evidence she was on the prowl, or that she was hoping to have a career in the local convent. What is clear though is 30 years ago, when I was around that age, a 15 year old virgin was rare. Maybe she was the exception, and maybe she was not out to bag a celeb. But the opposite might have also applied.
Lastly, I'd put cash on the likelihood that there's been some jumping on bandwagons, but the process is as it is, and has to be gone though.
