If the national innocence rate were 6% instead of the estimated 4%, then innocents in / outside California would respectively have 11% / 47% exoneration chances. Note well that the authors of Rate of False Conviction--one of the two sources for the nationwide 4% estimate--adopt the baseline assumption that so much attention is given to death penalty convicts that an innocent's exoneration is ultimately guaranteed, if only he survives for a long enough time. California's grossly sub-par exoneration rate renders that assumption impossibly conservative.
