It is nothing again family members, Imo, but we have seen other cases where picketing with signs etc. has taken place, and for one thing, it does not seem to work in bringing the person forward in any way desired by the family, as in Dylan Redwine's and Kyron Horman's cases, and also can turn ugly and ultimately ridiculous, as in Casey Anthony's case. It also incites the internet and possibly innocent people are subjected to some really horrible stuff, digging into their backgrounds, threats and more. All jmo
Also, if anything, these events tend to make the person targeted far less open to speaking with the families, Imo. They already know they are seen as hiding info and likely feel they won't be able to change their minds, especially if they have told all they know.
I empathize with Christina's family and the other families, as I know my late mom would have done anything under the sun...but logically, Imo, it does not help in the long run. Maybe a little added press for a few days...but the story becomes more about the one being targeted rather than the missing or murdered person in a hurry.
Jmo,etc.
