Mealey's (March 29, 2018, 12:07 PM EDT) -- RICHMOND, Va. — The Fourth Circuit U.S. Court of Appeals on March 28 upheld the conviction of a former Navy director of intelligence for illegally paying a California machinist $1.6 million in government funds to make 349 untraceable gun silencers for the Navy that did not work, finding in part that the trial court properly admitted testimony by the government expert who tested the silencers (United States v. Mark Stuart Landersman, a/k/a Mark Stuart, United States v. Lee Hall, Nos. 16-4066, 16-4067, 4th Cir., 2018 U.S. App. LEXIS 7755)....
