Speaking of "The World", this is a global problem, not just a couple of countries. There are missions in probably almost every country of the globe, even those countries that don't allow missions (they are underground or under the cover of humanatarian causes).
So logic would decree that the best people to make a real noise about this are people who have traveled internationally and have a working knowledge of other cultures and mission subcultures. Ummmm wonder where we can find such a group of well qualified individuals
Oh silly me, it's me, it's you, it's the MKs who haven't spoken up yet and it's the parents of the abused

Wouldn't it be nice to leave the world a safer place for the next generation by putting a bit of effort in ourselves. Never know, might even be a few riches beyond the Pearly Gates for those who care for the future children, I think I read something to that effect once.
