"Rehabilitation" usually comes after an appropriate criminal punishment being issued and received, not before. That reasonable people think that getting just twelve weeks in jail for his crimes -- which he at no point admitted -- is an offensive undersentencing in no way justifies their description as a "mob".
That is a bit disingenuous. This isn't people thinking that the justice system should have slapped him down harder. This is people who drop into every thread where his name comes up and insist that it should never just be "Brock Turner", but rather "The Convicted Rapist Brock Turner."
Arguably the biggest argument in support of the justice system failing in this case is that it did not deter this kind of vigilante attitude; that is an important part of why the system exists in the first place.
