That being said, was what they did for their son all that bad? Their teen aged son engaged in horrible behavior, he got found out, he got counseling.
They sent him to counseling that teaches God will reward you with extra faith and zeal for being abused, that abuse happens because the victim somehow invited it, that you can choose to not be abused sexually or have greater faith (guess which they say is better?) and that the fix for the physical abuse is to dedicate your body to God so you can cast out fear of marriage intimacy.
Oh, and at the counseling... the founder and leader of the "counseling center" resigned for having inappropriate relationships with over 30 teenagers, the state trooper (member of their church) who kept it quiet was put away for 50 years for child pornography, the brother's founder and one of the counselors at the center was outed for carrying on an affair with multiple secretaries for years and the head of the ministry at the center was let go for getting caught cheating on his wife.
Some group they got there.
Should they have called the police?
Fuck. Yes.
