Nod to invegauser for outlining the normal scope of the FBI. From that, I still believe this request doesn't naturally fall to their responsibility.
That said, I also acknowledge, and appreciate, cduggles bringing more to the table that both supports this NOT being typical FBI responsibility, but that there exists a path for the FBI to take it on - specifically at the request of the President.
TLB: You are correct. I never stated "Kav" was specifically mentioned in the article in which two letters signed by over 1,000 students who attended "Kav"'s school, as well as its brother and sister schools around the same time felt compelled to highlight the rapey culture therein described.
I'm always careful with my allegations, just in case Trump sends the DOJ after all of us (except a couple of like-minded fellows!!). Oh wait, he hates druggies...we're all going down. %)
Next: Here is a nice cut and pasted article and two other linked stories that explain why...
Can the FBI investigate the allegation against Brett Kavanaugh? Analysis: President Donald Trump said investigating Christine Blasey Ford's accusation of sexual assault against Brett Kavanaugh "is not really their thing."

Almost an FAQ on "Kav" and various groups involved in SCOTUS confirmation and evaluating his rapiness:

So yes, Trump would actually have to care about the truth. Ha. Ha.
So...there exists a means for the FBI to investigate, which is solely at the request of the President? Ok, I have that. Thank you.
Can you come back to WHAT they would investigate? Because they have already investigated him SIX times and found nothing. It seems hard to believe after SIX background checks they didn't find ANYONE to mention ANY of this 'rapiness'

I suppose, they could have been ineffective with their investigation...all SIX times. I've never been investigated by them, but a friend was when she applied for a gov't job. She shared that they even talked to her mailman and hair dresser (perhaps embelleshment, but the point remains - the FBI are really f'n thorough, it's their job).
Still waiting for anyone to respond to what to investigate. A location she can't remember? Witnesses who say they weren't there? Nobody has denied there wasn't a promiscuous environment for teenagers in that time and place. Nobody has shown Kavenaugh was part of it or did anything wrong as yet.
And before anyone points to 'more accusers!', they ALSO have not provided anything of proof, and have had their witnesses deny it happened. And, with each additional person coming forward, it begs the questions - why wait until now, with less chance of proof? why are the claims brought through political channels rather than legal which will in fact investigate (if there is enough to investigate - as local law enforcement, without political party bias)? why are there STILL no witnesses that support these claims or anything of evidence beyond an accusation? Just because more people claim it, doesn't make it true. It makes it more likely, but not true without proof. And these questions undermine their additional claims.
PS - I'm not sure if you are mocking me for using "Kav" or not (don't care). But ftr, I'm just to lazy to keep typing his whole name.
