I agree: "Yes, women lie."
No, I do not agree: "That's why there are so many unfounded claims."
Totally without substantiation. May be true...may be not.  
I believe the reason there are "so many unfounded claims"--finally, this series is getting closer to it, here-- the language is vague.  The reason many--maybe even most--files are closed is "insufficient evidence."  

What that means is...the police can't proceed because either the Crown will throw out the case before it gets to the courtroom or the judge/jury will rule not-guilty for...lack of evidence (meanwhile, complainant and defendant both suffer public humiliation and ridicule.)

Re: women's "border line personality issues"--really difficult to spot, sometimes, because they are, well, borderline.  Besides, many of the men who miss those issues...suffer from them, too.
