Protection of Freedoms Bill

I have one second point before my noble friend rises to answer. I accept that people who are not regulated can still be CRB-checked but the employer cannot get barring information. Unless the person has committed a crime and got on the police records in that way, the employer who voluntarily carries out a CRB check still does not know if that person has been barred. I understand that Sir Roger Singleton claims that 20 per cent of the people on the barred list have never been in contact with the police. Could my noble friend clarify that?
