It is worth pointing out that there was an alleged incident above. Authorities were not notified, and a trial did not happen. It is wrongheaded to infer that more incidents have likely happened due to the alleged incident mentioned here. I would still urge that poster to go to the authorities and have them look into it.I answered that question at some length in THIS POST. Rather than rewriting that post, I'll add some points that I think are worth considering.
1) Just because we don't know of incidents at a show doesn't mean they didn't happen. Sexual crimes are among the least reported crimes due to a number of things. There was at least 1 incident mentioned above, so it sadly makes sense that others have likely occurred.
2) Many organizations (I mentioned my own church in the previous post) recognize that waiting until there's an incident means waiting until it's already too late for someone. The ONUS is on the organization to be sure that measures are in place to prevent abuse from occurring.
3) There is NO substitute for a parent being responsible for their own child. I think everyone in this conversation knows that. The primary responsibility of keeping a child safe is on the parent. However, recognizing that responsibility doesn't mean that organizations should not have a plan in place for child safety.
4) Having a plan is better than not having a plan. If there are aspects of the plan that could be better, then dialogue about that is helpful and necessary. I'm not sure I understand why anyone would argue against having a plan.
I see no problem with background checking the volunteers. All else seems overblown in my estimation.
