Barrye Browne, Daron Calhoun

FILE – In this June 17, 2016, file photo Barrye Browne, left, and Daron Calhoun collect memorials placed at Mother Emanuel AME Church in Charleston, S.C., on the anniversary of the killing of nine black parishioners during bible study. The gunman who killed the worshippers had been arrested on drug charges just weeks earlier. Although that arrest should have prevented him from purchasing the pistol he used in the attack, the examiner reviewing the sale never saw the arrest report because the wrong agency was listed in state criminal history records.
