You need to read John Pavlovitz’s open letter to Brock Turner’s father in full. He responds to this horrible outcome much better than I could possibly:
I need you to understand something, and I say this as a father who dearly loves my son as much as you must love yours:
Brock is not the victim here.
His victim is the victim.
She is the wounded one.
He is the damager.
If his life has been “deeply altered” it is because he has horribly altered another human being; because he made a reprehensible choice to take advantage of someone for his own pleasure. This young woman will be dealing with this for far longer than the embarrassingly short six months your son is being penalized. She will endure the unthinkable trauma of his “20 minutes of action” for the duration of her lifetime, and the fact that you seem unaware of this fact is exactly why we have a problem.
