If I was H.B., and had done what he did, I'd be thanking my lucky stars that I received the sentence that was imposed here. It's good for him, he more than deserves it, and I could easily justify a much, much more onerous sentence.
I certainly wouldn't have filed an appeal. Which (rightfully) loses anyway.
Don't hold women down while they're unconscious and you're friend's having sex with them. Much less call "dibs" to be the next rapist.
These are not lessons that should have to be taught.
