A.C. Thompson has a devastating piece in The Nation this week describing the all-white militia that took up arms to defend one of the few neighborhoods in New Orleans to stay dry after Hurricane Katrina broke the levees in 2005:

Facing an influx of refugees, the residents of Algiers Point could have pulled together food, water and medical supplies for the flood victims. Instead, a group of white residents, convinced that crime would arrive with the human exodus, sought to seal off the area, blocking the roads in and out of the neighborhood by dragging lumber and downed trees into the streets. They stockpiled handguns, assault rifles, shotguns and at least one Uzi and began patrolling the streets in pickup trucks and SUVs. The newly formed militia, a loose band of about fifteen to thirty residents, most of them men, all of them white, was looking for thieves, outlaws or, as one member put it, anyone who simply "didn't belong."

It started out as a classic case of white paranoiac overreaction to fears of looting and rioting and whatever else it is those black people do -- rather like the reaction you saw in sundown towns in the 1920s, which were similar in being "defended communities," to supposed threats of black depredations -- but quickly morphed into something else altogether:

Fellow militia member Wayne Janak, 60, a carpenter and contractor, is more forthcoming with me. "Three people got shot in just one day!" he tells me, laughing. We're sitting in his home, a boxy beige-and-pink structure on a corner about five blocks from Daigle's Grocery. "Three of them got hit right here in this intersection with a riot gun," he says, motioning toward the streets outside his home. Janak tells me he assumed the shooting victims, who were African-American, were looters because they were carrying sneakers and baseball caps with them. He guessed that the property had been stolen from a nearby shopping mall. According to Janak, a neighbor "unloaded a riot gun"--a shotgun--"on them. We chased them down."

Janak, who was carrying a pistol, says he grabbed one of the suspected looters and considered killing him, but decided to be merciful. "I rolled him over in the grass and saw that he'd been hit in the back with the riot gun," he tells me. "I thought that was good enough. I said, 'Go back to your neighborhood so people will know Algiers Point is not a place you go for a vacation. We're not doing tours right now.'"

He's equally blunt in Welcome to New Orleans, an hourlong documentary produced by the Danish video team, who captured Janak, beer in hand, gloating about hunting humans. Surrounded by a crowd of sunburned white Algiers Point locals at a barbeque held not long after the hurricane, he smiles and tells the camera, "It was great! It was like pheasant season in South Dakota. If it moved, you shot it." A native of Chicago, Janak also boasts of becoming a true Southerner, saying, "I am no longer a Yankee. I earned my wings." A white woman standing next to him adds, "He understands the N-word now." In this neighborhood, she continues, "we take care of our own."

Janak, who says he'd been armed with two .38s and a shotgun, brags about keeping the bloody shirt worn by a shooting victim as a trophy. When "looters" showed up in the neighborhood, "they left full of buckshot," he brags, adding, "You know what? Algiers Point is not a pussy community."

... Some of the gunmen prowling Algiers Point were out to wage a race war, says one woman whose uncle and two cousins joined the cause. A former New Orleanian, this source spoke to me anonymously because she fears her relatives could be prosecuted for their crimes. "My uncle was very excited that it was a free-for-all--white against black--that he could participate in," says the woman. "For him, the opportunity to hunt black people was a joy."

"They didn't want any of the 'ghetto niggers' coming over" from the east side of the river, she says, adding that her relatives viewed African-Americans who wandered into Algiers Point as "fair game." One of her cousins, a young man in his 20s, sent an e-mail to her and several other family members describing his adventures with the militia. He had attached a photo in which he posed next to an African-American man who'd been fatally shot. The tone of the e-mail, she says, was "gleeful"--her cousin was happy that "they were shooting niggers."

I'm just waiting for some Republican to tell us once again that "racism is dead."
