Louisiana Governor Kathleen Blanco says that the guardsmen are allowed to open fire on "hoodlums" taking advantage of from the devastation by Hurricane Katrina. "

These troops are fresh back from Iraq, well trained, experienced, battle tested and under my orders to restore order in the streets," Blanco says.
