Workers Put up Protective Scaffolding After Deadly Debris Accident in New York

One day after a prominent architect was killed near Times Square by falling debris, workers put protective scaffolding over the sidewalk. But the newly installed scaffolding comes too late for Harvard-educated architect Erica Tishman. Sadly, she's not the first to be injured, and in some cases, fatally struck by falling debris. Greta Greene, 2, was killed in 2015 when a brick fell on her as she was sitting on her grandmother's lap on a bench in New York.
