I personally don't think there is any perfect justice system. We have innocent people in jail here... I for one think she was involved with it and decided to go down with the boyfriend. It wouldn't be first time a female was that stupid nor unfortunately will it be the last time.
Now having stated all of the above, let me also ask a question... If Meredith had been the one convicted, and AK be the one dead would we be having this discussion?
