Yes you do need to prove Jackie's story, or at least support it.

A commentary on "We Don’t Need to Prove “Jackie’s” Story "
http://msmagazine.com/blog/2014/12/11/we-dont-need-to-prove-jackies-story/

” When I heard that Jackie’s story was being questioned, though, my reaction was slightly different from that of my peers: My first thought was, “So what?” ”
So they already attacked the reputation of an entire frat and by extension everyone in it. They already shut down fraternity activities on the basis of this report. So it’s kinda important if it might not be true.

” but a larger part of me knows that the real devil is the rape culture that pervades college campuses.”
Then you should be looking at whether there is any evidence of said “rape culture” instead of claiming it doesn’t matter if an accuser told the truth. When Jackie’s word was undoubted, it mattered, it was evidence of both horrendous evil and official negligence of that evil. Now that it seems like her story isn’t true it’s irrelevant. Well which is it? Either accusations her case matters or it doesn’t. 

“it doesn’t matter if Jackie’s story is discrepant in some areas.”
Nor does it matter if those discrepancies prove it’s a load of codswallop. And that’s the point. You don’t care about the truth, so why should we listen to you?

“What matters is that I have lost count of the number of friends who have been assaulted in my three-and-a-half years on campus.”
Then why not write about their cases rather than one of the most inconsistent accounts of criminal activity I’ve heard since the Hilton Hotel bombing?

“nothing will change how her story rang true for too many college women. I know it rang true for me.”
Then it rang true despite obvious and serious contradictions. Which means we can’t take your word for it that any of the other cases that “ring true” for you are true.

“When I told this story to my friends recently, the men looked at me in disbelief. But the women nodded their heads in agreement, as every one of them had experienced something similar.”
Really? Every single women in your social group was sexually assaulted? Even assuming that we take feminist numbers seriously (and God knows that’s a stretch) how likely is it that everyone had that experience? Even if you told only 4 friends at 1 in 4 that’s a 1 in 64 chance that they were all assaulted. On the other hand how likely is it that they all heard stories like yours, maybe about a
“friend of a friend”? Quite likely. 

“Look up the pages upon pages of similar stories that women shared ”
Well the first one is similar in that it’s completely non-credible. She says that she decided to pursue it through the university because of privacy concerns, but “The police discouraged me from pursuing it criminally, saying that I didn’t have enough evidence to win.”. So which is it? Did the police tell you you had no chance or were you worried about the privacy?
The woman continues: “(I didn’t want future employers to Google me and see that I brought forward rape charges), ”
Really? That’s what she didn’t want employers to know? Is there any evidence that employers discriminate on that basis? Or did she not want them to know that she had made FALSE allegations? She claims she has all this evidence, yet nobody seemed to agree. She also claims that “Nicole Eramo … later told me she didn’t believe the studies that showed rapists, in particular, were repeat offenders of this heinous crime. “. Is that likely? Is it likely that someone would dispute a well-known statistic that isn’t disputed by anyone I know of, even MRAs who dispute almost everything feminists say is true. Look kindly stop taking anonymous reports as gospel and we’ll all be better off.

“One questionable account does not change the fact that the problem with rape cases isn’t false reporting; it’s underreporting. ”
Right because there can only be one problem with rape cases. Tell that to Brian Banks you ludicrous “reporter”.

“This is what we should take from Jackie’s story, whether it’s fully accurate or not:”
Or indeed accurate at all or not.

“Being a woman on a college campus today means feeling, at times, threatened, abandoned and scared. ”
No that’s not what you can take from this story. What you can take from it is that women can get their accusations taken seriously despite massive holes in their story, and whole fraternities of men can get punished unjustly and people like you don’t even apologize.
If you want to take the another lesson from a story, find another story. Or make one up, AGAIN. And yes I’m implying that you made up the story of your sexual assault.
