Fort Worth Symphony Orchestra music director Miguel Harth-Bedoya ran afoul of strict — some say ridiculous — security procedures imposed back in January by Performing Arts Fort Worth Inc., the organization that owns and runs Bass Hall. The rules forbid any bags or purses larger than 12 by 4 by 12 inches. Luggage, backpacks and shopping bags are not allowed, and bags or purses larger than 5 1/2 by 8 1/2 inches must be inspected. Ushers and security personnel have been scrutinizing arriving audience members and inspecting larger bags.
