Fishy Disclaimer: Kendricks was never criminally convicted beyond reasonable doubt of abusing Candace and maintains his innocence.
Now that's interesting that you mention (what amounts to)innocent before proved guilty. Yet you think authorities should legislate to ban people from churches before they commit a crime. Where else should the law ban them from? Supermarkets, colleges, pool clubs, football grounds, fitness clubs?
Strange for a Christian to want someone banned from a church before they have sinned, too.
Why all these diversions from the basic, common sense answer.
If someone commits the crime of child abuse and it is reported to an elder, the elder reports it to authorities. That simple.
