Children from stable families tend to manage to stay away from sex assault charges, and resolve the issue without criminal liability. Children from unstable families do not have the same luxury. It is unfair but it us life. I wish i could say Juvy and foster care reforns kids, but it is just not true.
Many posters seem the think he should have gone to at least Juvy and been labeled a sex offender. I guarantee the end result would have been far worse. The son would have been a pariah for the rest of his life, the family and victims ostracized, and he would be MUCH less likely to reform and more likely to recommit a crime. You do not want a kid like that with the wolves in the Juvy system.
Getting CPS involved could have resulted in their kid in a foster home, part of another abysmal system.
Going to the secular authorities should be the last resort, not the first. Try to resolve in the family, then the Church, and if you feel it is the only way to keep others safe. secular authorities.
It is a terrible situation to be in, but the family is sacrisanct, and you only willfully give up your children in the most dire of circumstances.
