The WT got it right.
Besides, it is one of the nicest sounding parts of the bible, but it's only make-you-feel-good-BS. If we were to use Jesus' standard for prosecuting someone, it would be impossible to prosecute the worst criminals, let alone an adulterous woman. Also, it is quite inconsistent for Jesus to claim to uphold the law in some parts of the New Testament, but break it so he can be praised for his ridiculous solutions to conflict, such as "turn the other cheek". Pleeeeeeease!
