As it happens, I turned out to be a teacher, and I'm an adult instructor for the ACF. I can promise you that these days the background checks are, happily, far more stringent. So yes, back then there were far more nonces. Now there aren't.
Sadly not the case with my son's cub leader.
This was only two years ago.
The wonderful and longstanding group of leaders had been wanting to retire for some time but kept hanging on because there were no new volunteers coming forwards to run the pack.
Suddenly they announced that they had found two young and enthusiastic men who had come through the ranks of the scouting movement.
They had a phased handover and then took over fully.
They were useless to be honest. They couldn't control the kids and had zero personality. They were not my idea of positive make role models. One was socially inept and the other showed a serious lack of personal hygiene.
They lasted about six months and left very suddenly so the old leaders came back out of retirement.
It came out after one of them was arrested , charged and convicted of grooming 12 year old boys and downloading indecent images of children , that he had had a police record of doing the same thing 5 years earlier.
We tried to contact the senior area leaders to get to the bottom of why this wasn't picked up in the back ground checks but gave up in the end as the it was obviously all being swept under the carpet.
I removed my son as even though the original leaders had returned and were wonderful I had no faith in the senior leadership to protect the boys.
