For two reasons:-
1. The volunteer sector has been a key part of our national life for many years. It is also a key ingredient in maintaining communities, especially important now that technology drives many into electronic rather than personal communication. Many volunteers are retired people, who grew up in an era of individual responsibility. They are used to being responsible and to being respected. Vetting them is seen as an insult to their integrity. If the Government wants to help restore the concept of community, removing this cancer will be an important step and a vital signal that they mean business.
2. State vetting of volunteers is an infringement of civil liberties. It is also a catchall sledgehammer to crack a nut. Many voluntary organisations have never had the sort of problems which vetting, with its secrecy and suspicions, is supposed to address. Making all volunteers feel a sense of guilt, such as when one is called to the headmaster or a policemen apears at the door, is a deterrent to volunteering. Many will quit the sector rather than accept it. I know. I drive for a privately run hospital car service. Several of us will resign when vetting becomes obligatory, which is promised for next year. In my case I have nothing to hide and have been vetted as a Civil Servant. But as a volunteer I will not play along with this authoritarian big-brotherism.
