Even though people may pick apart their appearance... I think they made the right choice in speaking. *I* feel a lot better now, hearing from the family... We love you, we miss you, we want you to come home. I feel like the step father and the mother are not going to be picked apart, just as they were not before.
Terri, is just going to be picked apart no matter what she does... it's just how it's going to be. At least now she has appeared in public, she cared enough to go to the press conference. They all tried to show a united front. All of those things will just be less for people to pick apart.
Although I do not know if it will impact the search for Kyron directly...
I think even more people may come forward to help now. Donate to the search effort, call in tips that before they thought might not be important, just motivated by sympathy.
I think it was a good thing. I am heartbroken for Desiree... I cannot even imagine.
