[Gretna] and its police received considerable press coverage when, in the aftermath of Hurricane Katrina on August 29, 2005, people who attempted to leave New Orleans on foot using the Crescent City Connection bridge to cross the Mississippi River were turned back at gunpoint by officers from the City of Gretna Police, Crescent City Connection Police, and Jefferson Parish Sheriff's deputies guarding a roadblock that had been set up on the bridge in the days following the hurricane. According to eyewitnesses, some officers threatened to shoot those coming from New Orleans as they attempted to cross into Gretna on foot, shots were fired overhead, and downdraft from a police helicopter was used to help clear refugees from the bridge. New Orleans Police Department 911 operator Patryce Jenkins, having walked the city for two days after her dispatch center was flooded, tried to return to her unflooded Gretna apartment via the bridge. Though she had ID to prove her status as a resident, she said instead of checking it police ordered her to turn back, used racial slurs, and fired a warning shot over her head, leaving her crying in disbelief.
Gretna mayor Ronnie Harris pointed out though the city had not flooded, Gretna had been severely damaged as well, losing power, water, and sewage services, claiming the city had no food, no water, no shelters, and no capacity to take refugees. Harris said that the city had commandeered buses and been transporting a crowd of about 6,000 refugees to a nearby FEMA facility. But he said the city enacted the blockade after a spate of door-to-door robberies began in Gretna and stores at the Oakwood Mall were looted and burned.
