Nation: What are mercenaries doing in New Orleans?

"This vigilantism demonstrates the utter breakdown of the government," says Michael Ratner, president of the Center for Constitutional Rights. "These private security forces have behaved brutally, with impunity, in Iraq. To have them now on the streets of New Orleans is frightening and possibly illegal."

Blackwater is not alone. As business leaders and government officials talk openly of changing the demographics of what was one of the most culturally vibrant of America's cities, mercenaries from companies like DynCorp, Intercon, American Security Group, Blackhawk, Wackenhut and an Israeli company called Instinctive Shooting International (ISI) are fanning out to guard private businesses and homes, as well as government projects and institutions. Within two weeks of the hurricane, the number of private security companies registered in Louisiana jumped from 185 to 235. Some, like Blackwater, are under federal contract. Others have been hired by the wealthy elite, like F. Patrick Quinn III, who brought in private security to guard his $3 million private estate and his luxury hotels, which are under consideration for a lucrative federal contract to house FEMA workers.
