Should there be a registry for domestic violence offenders?

Thanks to this post at Crime & Consequences, I see from this local news article that Pennsylvania legislators are considering a bill to create a registry and database of persons convicted of a domestic violence offense.  Here are more details from the article:

Two years after a man shot his wife and later killed himself in Quakertown, officials in the Upper Bucks borough will likely urge commonwealth legislators to create a state-wide Internet registry of domestic violence offenders to help prevent such tragedies from happening again. Borough council expects to approve a resolution tonight calling on the Legislature to pass a bill known as “Robin’s Law.”

Introduced in the state House on May 31, the bill would create a Megan’s Law-style database. Instead of sexual predators though, the picture, address and crime of domestic violence convicts will be posted online for anyone to see, according to a preliminary draft of the bill.

Though I have not seen much firm empirical evidence, I have heard lots of anecdotal reports from various sources that sex offender registries can be a helpful and effective law enforcement tool.  If this is true, my first instinct is to support broader use of offender registries.
