If he even got that sentence, let alone serves it.
It's also worth asking, why make yourself responsible for championing this person's cause? Why feel the need to bring it up, let alone defend him? Especially when you keep saying over and over again that he did what he's accused of. Are we just supposed to agree that it's simply not bad and shouldn't be a crime? Do you know personally exactly what happened or is every piece of information on the situation from him or through someone else he told? Because, again, sexual predators and abusers LIE and stretch the truth...a lot. They omit key information and like all human beings, they tell the story from their perspective and to their interest.
I'm all for shades of grey in a lot of areas...but I'm really not into finding ways to defend pedophiles. If it's about criminal justice, there are great examples of people who have been fucked over by the justice system, even when guilty of their crimes, who aren't child molesters or sexual predators in general. There's always a possibility for disproportionate response in any crime, but it doesn't mean we have to be ok with it or support the perpetrators.
