"Meeting on the grounds of the former Confederate Capitol, the Virginia General Assembly voted unanimously Saturday to express "profound regret" for the state's role in slavery.
Sponsors of the resolution say they know of no other state that has apologized for slavery, although Missouri lawmakers are considering such a measure. The resolution does not carry the weight of law but sends an important symbolic message, supporters said.
"This session will be remembered for a lot of things, but 20 years hence I suspect one of those things will be the fact that we came together and passed this resolution," said Delegate A. Donald McEachin, a Democrat who sponsored it in the House of Delegates

These guys may be hungry for praise but they are not stupid. If they had really said "apologize" that would have been an admission of liability. "Regret" means nothing. We all regret lots of things. I regret the First World War but that does not mean that I apologize for it.
