A childrens prison also known as a contact centre

Social services have a child in foster care for 'at risk of emotional harm'.He was once a normal boy who enjoyed life and being with his mum and dad who apart from having their difficulties in their marriage were eventually teared apart by social services and the family court.Here is another video of the little boy who regulary attacks social and contact workers because he wants to go home with his mum.They restrain him and still will not admit to causing my son 'actual emotional harm'. Who are the child abusers?
