The prisoners on death row weren't taken off of it when NM, MD and CT abolished the death penalty? That sucks...
No, because the law was not made retroactively.
CT still has 12 on death row, MD 4 and NM 2.
Plus, Wyoming has the death penalty - but nobody is currently on death row.
IIRC, O'Malley did promise to review each case and he's still got time until January to clear the death row, if he chooses so. On the other hand, he seldom exercises his powers of clemency as compared to previous Governors (and, it seems, his successor, as Hogan said during the campaign, he "would take a greater interest in clemency requests").
