You're wrong. The calm family is his, and they don't seem surprised at all.
I see that now, his mother was praying before the verdict was read. However, it does not surprise me either and I'll explain why.
I work for a defense attorney on wrongful accusations/convictions. I've learned a great deal from some of the heartbreaking families that I've worked with.
When your family member has already been falsely accused, devastatingly arrested, incorrectly charged and unjustly tried... you become jaded... less than optimistic... numb.
I mean think about it for a moment.
Your family member one day is accused of a crime they didn't commit.
You believe the investigation will determine that.
Then, they are arrested.
You believe they can just explain their side/provide an alibi and prove their innocence.
Then they are CHARGED.
You believe the mistake will be realized before trial.
Then TRIAL starts.
Each step is like a further nightmare that never ends.
It actually becomes easier to convince yourself that they will be convicted rather than hope they won't. So you can prepare for the worst, find the silver lining in that (well the kids still HAVE their dad, he isn't dead at least type of thing.)
By the time you get to the verdict there are two types of people. Those who have been emotional throughout and are now stoic. Or those who have been the strong stoic ones throughout and lose it at the verdict.
Also, I think most realize that in this case it was almost certainly either the father or the son. So that would complicate matters greatly for both the family and the jury.
It's a horrific situation and I don't claim to know the truth. I just don't believe the state met it's burden here. Whether he's guilty or not, I don't believe the verdict is correct.
