Cruelty to animals, it is said, is often a precursor to graver crimes. So would there not be some usefulness to a registry of individuals convicted of felony animal abuse? Legislators in California want the Golden State to be the first to establish such a record — just as California was the first in the nation to create a registry of sex offenders.

The goal of the registry, which would list crimes against both pets and farm animals, is to make it easier for shelters and animal-adoption groups to identify people who shouldn't be allowed access to animals. It would also be a boon to law enforcement because animal abuse, the bill's authors' say, often escalates to violence against people

I do not think a law enforcer - a police nor a judge - can extrapolate from animal abuse registry to say some may be guilty of spousal abuse.

If there isn't one, let's have that first!
