Louisiana district attorney has decided not to defend before the Supreme Court the conviction of an intellectually disabled teenage boy charged with robbery and murder. The Washington Post reports that prosecutors in the case failed to provide the teen's attorneys with recorded witness statements that could have undermined prosecution witnesses, including the only person who claimed to be a witness to the shooting. The Post reports that the recorded statements suggested that the teen may have been set up. Mary McCord and Douglas Letter, two litigators and visiting professors at Georgetown University Law Center, examine the ramifications of prosecutorial mistakes and withholding evidence in this analysis at The Post.
