CHARLESTON, SC - JULY 16: Judge J.C. Nicholson makes a point on a gag order for the pending trial of Dylann Roof at the Judicial Center July 16, 2015 in Charleston, South Carolina. Roof is charged with murdering nine worshippers at a historic black church in Charleston last month. The South Carolina Press Association is challenging a decision by Judge Nicholson made last week on potential trial participants as well as banning the release of documents in the case, including 911 police dispatch calls, coroner's reports and witness statements.
