No, that isn't really true, and my evidence is the Elizabeth Smart case.
The Smart family was under the gun, every man in the family young and old was being blamed all over the internet and the media, and the mother was a basket case.
But guess what? They banded together and kept going on the news week after week, and the father who was suspected of foul play kept talking about his daughter until she came home.
I was someone who thought many people in the Smart family might be guilty of something. But I was wrong and I feel bad about that.
However, in hindsight, a major clue to their innocence was that they never lawyered up and stopped talking. They let their emotions show and they didn't care what the world thought.
So no, I don't think it's wise of Terri to clam up when her stepson is missing, especially now that she is under the gun. I've been wondering for weeks why she doesn't speak out and at least try to show her feelings for Kyron. The longer she stays silent the worse it will be in front of a jury.
My point is the family turned against Terri (not that I wouldn't with a MFHP in her back pocket! Sheesh!) and the Smart family never pointed fingers at one another, they stuck together. So I think this is a little different situation.
