The ACLU has jumped into the Karen Read Supreme Judicial Court fight on the side of the accused murderer. The American Civil Liberties Union of Massachusetts filed a brief in Read’s appeal to Massachusetts’ highest court to have two of the three charges against her — including second-degree murder — dropped in her second trial scheduled for January.
