Few problems from evacuees at shelters (Sept 9th)
FORT WORTH _ Police say they have encountered few problems in Fort Worth shelters filled with Hurricane Katrina survivors.
Officers have responded to a handful of disturbances, but no more than should be expected, spokesman Lt. Dean Sullivan said.
"Any time you have a large-scale population in stressful situations like this, it is inevitable that a few things will happen," he said. "But, by and large, we aren't seeing serious problems."
About 2,200 evacuees were registered Thursday afternoon in Tarrant County shelters..."
