I agree that it was realistic....and predictable that they were going to vote not guilty when the judge informed them of the plea.
I hope the mother and the girl never find out how the jury was going to vote.
As a mother of three daughters, ages 18 - 24, I was unsettled with the fact that she could have had her freedom if she had not gone with the plea deal. Now she serves at least 10 years, and her life after prison will always have that attached to it.
I couldn't help but put myself in the mother's position.
