This case has always been a difficult one with a number of factors that both mitigate and enhance her guilt. She was 16 and a victim of sex trafficking, yet her crime was the shooting and robbery of a sleeping john. Maybe the 15 years she will have served is closer to the right amount than the 51 to life that she received. This Wikipedia piece fleshes out the case a bit for those unfamiliar with it. I tend to be a hardliner when it comes to violent criminals, but this is a tough call.
