Black man convicted of Shreveport, La. murder by all-white jury spends nearly 30 years on death row, in solitary confinement before he’s exonerated. Allegation: Law enforcement fabricated evidence, withheld exculpatory evidence, among other misdeeds. (The lead prosecutor has since apologized.) The defendants answer the complaint but later move to dismiss it. District court: It’s too late to try to dismiss. Fifth Circuit: And it’s too early to appeal that ruling. Go deal with the merits of the case.
