Some congregations have formal arrangements and rota's to pick up the car-less, elderly, infirm, or disabled (physically and mentally) for meetings.
Those that are asked to help with lifts should be police checked, since they may be alone with children (ie if parents can't make the meeting but pack the kids off) and vulnerable adults on a regular basis.
If there's a known pedo in the congregation they should be fully banned from the field ministry, any privileges and all platform items, since the elders useless 'monitoring' is not regulated, coordinated or even sustained, and a determined offender will always find ways to work around it.
When an offender moves to a new hall there should be some alert for the families there, and not just the families of the elders who would know and can protect themselves.
When an allegation of abuse is made it should be the police who investigate, not a retired florist, a seasonal potato picker and a part time sales assistant, none of whom were allowed any meaningful education. During that investigation the accused should not be permitted to go on field service.
