To stop discouraging people from the vital role of volunteering to work with children. This should be based on a database of those with criminal records NOT a database of innocent people.
The strict rules covering volunteers who work with children, etc should be relaxed. It should be up to each school, local authority, etc to make a decision on whether a CRB check should be required dependant on the circumstances of each case. E.G. if a member of staff is also present, how many volunteers are going to be working together.
