With no explanation, chose the best option from "A", "B", "C" or "D". Vaughn Index and In Camera Review Plaintiff has requested that the Court review a representative sample of documents in camera and order Defendant to provide a “Vaughn index” for the Redacted and Withheld Documents. The Court will not require either of these measures. In camera review is not required where the Court is satisfied that the agency has adequately supported their exemption claims. See Rugiero, 257 F.3d at 544. In addition, under Eighth Circuit law, no Vaughn index may be required where Exemption 7, the law enforcement exemption, forms a basis for withholding documents. In re DOJ, 999 F.2d at 1311 (error to require agency to provide Vaughn index detailing documents withheld when the basis for exemption was law enforcement purposes); see also Barney, 618 F.2d at 1273-74 (<HOLDING>).
