Kaine knows the answers to those questions. He believes Terri is responsible.
Desiree, through Kaine.also knows the answers to those questions. No "mystery" what she thinks.
So we see no "frustration"h from those closest to this tragedy. Only "we" ..."cannot judge".... if we ignore what that the people WHO KNOW THOSE ANSWERS...keep telling us.
One might not know how to operate a car because he's never done it. And I suppose if someone who drives everyday tries to tell that individual...that person can still reject their answers because they've never put a key in an ignition themselves.
People who know the answers are confidant that Terri is the person who hurt or killed their son.
There are cases, however, where even those closest to the situation suspect the wrong person.
For instance, in the Amber Dubois case, her stepfather, Dave Cave, was a suspect. He had no strong alibi for most of the day; he decided to buy his wife (Amber's mother) some flowers, brought them to her at work and hung around for almost an hour.
His wife considered this highly unusual behaviour; clearly, she would be in a position to know. That atypical loving gesture became just one of the reasons why Amber's mother began to suspect Dave Cave of being responsible for Amber's disappearance. It just seemed so hinky, why would he do something different (for him) on the very day Amber disappeared?
It soon seemed like there were so many things he'd done that day that seemed suspicious.
And then he took and apparently failed 8 (eight) polygraphs.
His wife left him, believing he had killed his stepdaughter.
Finally, the real perpetrator (John Gardner) unexpectedly confessed and told LE where to find Amber's remains.
Without context, I have no way to know how accurately KH's and DY's judgment of people has been in the past, which would serve as an indication of how accurate their judgment is in this case.
I think it is more likely than not that KH, DY and LE are correct and TMH is responsible. Based on the publicly known evidence, though were I on the jury I definitely could not vote to convict.
That's why I want to know more.
