It's not difficult to appoint a judge as the chair. Judges chair these panels all the time. There must be a few retired Lady Justices kicking about who could do it.
So the choice of chair is between a former policeman (who's also an active Labour supporter) and a social worker.
Which three groups are most culpable in the whole scandal?
Police. Social workers. The Labour Party.
A cynic might think the whole thing has been designed to fail.
