I too thought at first that he would be good for the As, maybe help with their public image but after the "nanny did it" announcement I am not so sure.
At least, they seem to be keeping their mouths shut but the announcement about them wanting a private visit with KC was unnecesary. That could have been handled in private with the jail personnel. Then there is the whole thing with the toys at the memorial, that statement should have been made by the As.
They needed to handle this a little more sensitively.
First, they could have left them there a while longer. They could make a public statement that they appreciate the memorial and that instead of leaving a toy they would like for the toys to be donated in Caylee's name. They could also have let people know that all toys that are left at the memorial will be collected and donated to "name of charity here".
They could go down there and publicly pick out a couple of ones that they would want to keep in remembrance of her and make the announcement there at that time.
Tears would be good. Telling the public that they are grieving and understand that everyone else is as well and a little blurb about how special Caylee was to bring all of these people together would be nice.
Look through the memorial items, read some of the notes, take a couple of flowers, a toy or two. Make the announcement then leave.
this would have gone over so much better that having a lawyer make the statement or sending down a stranger. He/she obviously did not handle it correctly.
The As have a tendancy to talk when they should shut up and not talk when they should.
they need to garner the publics sympathy at this time, if that is even possible now and a nice statement from them showing the correct amount of grief would have done wonders for their public persona.
Then quietly go through their grieving process. People would respect them for these actions.
The lawyer could even have made the statement while they were at the memorial if they felt that they could not speak but making a public appearance with the appropriate emotions would be good.
