Four people were shot Saturday night on a packed Bourbon Street in New Orleans in the city’s Mardi Gras celebrations. One male victim had undergone surgery Saturday night and was listed in critical condition, while the other three were stable. The area remained crowded with revelers after the shooting, with many saying they were undeterred by the violence and others saying they were not surprised. “It’s kind of like that,” said Baton Rouge resident Lyle Robelot, 26. “You just hope it doesn’t happen to you.” No arrests were immediately reported, and police said they were pursuing three men who fled the scene.
