Yes and no child safety and where the crb rules run out is a grey area . I''ve been having crb and old style police checks done on me since I was 14 so it no longer bothers me.
The thing that does bother me is the checks only cover people who have been caught so in themselves are pretty pointless. They don''t save adults from malicious accusations which are frequent in senior schools or take into account a 15 year old boy getting a 15 year old pregnant would be a sex offender. The list goes on.
