Not only that but there has been a few police officers arrested for child abuse too. This is indeed a problem that spreads like a viral outbreak, or a wildfire.
This would be very difficult, granted abusers tend to be well integrated into an institution, and when new converts and or recruits are welcomed to the community, no one knows the intent of said recruit. This is like the whole gang stalking thing, a guy comes to the church and says he seeks God and want to follow Jesus, and he is welcomed, however his intent is to commit and subdue women into sexual immorality, you do not know until it is too late, but if you have wisdom in the signs, you can prevent an action.
That being said, this plague, the whole child abuse situation, cannot be 100% destroyed, you can only train people to prevent some instances of abuse, and educate the people and the public. But it seems not many people are welcoming of such and they later become shocked at situations that is beyond their control.
Sometimes justice is a double standard. They'll throw away the key to the cell of an abuser, but allow another abuser to walk free, allowing those who follow him to support him.
America is a broken and to some they find exploits.
