Based on the victim statements during sentencing...I wouldn't call that abuse. I'd call that Rape.
Just my opinion.
Rape and associated sexual crimes are heavily impacted by semantics and terms, run the gamut and vary widely.
I got this all into writing but wasn't fast enough to post it before more comments.
Here is some background regarding definitions:
As far as the term "Abuse" vs "Rape", the death penalty and Federal Statuary Sentencing Guidelines for sex offenses: rape falls under "Offenses Against the Person: Assault with Intent to Commit Sexual Abuse."
"Abuse" is a general term that criminal law and Federal Law defines several ways and includes "sexual abuse".
To me, "abuse" always sounds too mild for rape, but regarding Federal Statuary Sentencing, and Sex Offenses, it is accurate.
In December 2011 DOJ updated the definition of rape for the purpose of Use-of-Force reporting by agencies to the FBI’s Uniform Crime Report (UCR) Summary Reporting System (SRS). For reporting purposes, "Historical rape" refers to the old definition of "Forcible Rape". The definition was unchanged since 1927. The "new rape" definition dropped "forcible", removed gender and added penetration by foreign object.
From what I briefly read, Nassar's sex crimes were committed under the guise of actual medical procedures including one called a "Pelvic Floor Examination". From what I read, it was absolutely abuse and rape.
He pled but as I understand it, Nassar continues to say he is only guilty of performing medical procedures and not rape.
Probably more information then most people care to know.
He's a diseased animal that will always be a danger to life. That's my opinion.
