The main points here seem to be the background check. But it isn't the only issue. If one were to actually read the whole Youth Protection Plan they would see it is unworkable for most YE flights and rallys. In addition we would have to curtail many other programs. Finally the vetting and supervision of virtually all the volunteers at the events is onerous. Imagine at least two "supervisors" wandering around looking for any inappropriate behavior!
Add to this the requirement for each chapter or YE pilot to keep records of each child, their parents information for at least 3 years.
