I dont think the damage to Cindy will be done by LE. This is a self-inflicted wound that damages only her.
By failing to help the people whose job it was to find her granddaughter, shes harmed her own cause. Why will the public believe that shes convinced Caylee is alive and that everyone should be looking for her, when she went out of her way to thwart the investigators who were trying to find her?
The spin on this is that she didnt want to help LE even in the earliest days when many people believed Caylee might still be alive. For what reason?
