I think it more of a critique of what the false impression the public were given about the fcarers as we now know them were put out in the media as what the public considered were William's biological parents.
When there was a real grieving family of his real birth parents who were denied participation.
Giving a grieving father and grandmother an avenue to say something and be heard and to take the grandmother to the scene for the 1st time showed genuine empathy and compassion.
Not a critique of the fostering system but of policy from my perception.
