If FD's NSWCC case involves an assault, as FM's did, I think it is going to be a case of he said/she said - much like the actual alleged assault case against him seems to be.
The child says he put his hands around the neck.
He says he put his hands flat on the child.
The truth may lay in both of those statements. Meaning, flat on her shoulders and right by her neck on either side. A child's shoulders are small, an adult's hands are big.
If so, did he physically assault the child, or was he parentally restraining the child? (In the court's eyes.)
Therefore, did he lie about not assaulting the child - again, in the court's eyes. If this lying charge is about that.
