Religions should be held to a higher moral and ethical standard, but by the adherents of the religion or faith, not the government. If one is a member of a religion or even a social club that is hiding abuse, withdrawing support and membership will most likely bring about a "housecleaning."
Giving the government more power is not the answer, IMO. Any entity that is given more power becomes more corrupt. Are there no pedophiles in Communist countries where religion has less power? There will always be pedophiles and those who protect them.
This comment may be off topic, but here goes anyway: If clergy-penitent privilege is revoked, the most egregious sins will not be brought to confession. Then the clergyperson cannot refer the penitent for counseling or assist him/her to get the treatment or other help he/she needs.
We all have more power than we are taking. If we all do our own part as individuals, we can change the world.
The best answer is to educate every person in propaganda and brainwashing techniques and critical thinking skills as well as what is and is not criminal behavior, who is and is not a target/victim so that they won't make any organization so sacred that such organization is exempt from consequences for crimes.
In idealist mode,
