IMHO, like this:
1. Upon accusation, cut off all contact between child and molester.
2. Immediately take child for physical exam.
3. Immediately take child for psychological exam.
4. If allegation is supported, notify authorities
Persue prosecution if a supportable case can be made.
Oh, and if you are so inclined, you could notify the so-called "elders" at some point after #4. These men have no training, no inclination, and no ability to help you. Their main concern is glossing things over in order not to bring "reproach" upon "Jehovah's name" (as if being discovered later giving aid and comfort to a known molester doesn't accomplish the same thing). You and your child's problem are the least of their concerns. As the child's parent, your prime responsibility is the welfare of your children. So including the JWs anywhere prior to #4 is not in your child's best interest.
IMHO, that is.

Where it is a duty to worship the Sun you can be sure that a study of the laws of heat is a crime.
