That's a tough one. And I think these sentences need to be reviewed and some of them revoked.
However, the underlying problem was that these people who are currently in jail were doing something that was illegal at the moment. Their sentences need to be revised, but it's probably not something I'd exonerate from all guilt.
According to the Ex Post Facto law [1] definition, a court could issue amnesties or pardons for scenarios like this, but I don't think it would be an automatic process over all convictions.
