Crews continue to rescue New Orleans survivors September 6, 2005 at 4:45 PM CDT - Updated July 26 at 5:05 PM Boat rescue crews and law enforcement vehicles are scouring New Orleans, searching for people to rescue. One man with the Kentucky Air National Guard says in some cases, it's easy to get residents to leave. He says "They're sitting on the porch with their bags packed." Others are refusing to go. That's not O-K with the mayor of New Orleans. Ray Nagin warns the city isn't safe. He says the floodwaters are filled with toxic waste, dead bodies, mosquitoes and gas. He says water will no longer be handed out to those who refuse to leave. Meanwhile, an effort continues to get the evacuees back on their feet. The deputy director of the Federal Emergency Management Agency says hurricane survivors will receive debit cards so that they can begin buying necessary personal items.
