White supremacist Craig Cobb who was told he has black ancestry arrested

He came, he saw, he tried to conquer. Instead, he got arrested: Craig Cobb's attempts to turn Leith, N.D., into a white-supremacist enclave have hit a wall now that he's in a local jail, accused of terrorizing townsfolk.

But there's a new, ironic twist to his thwarted takeover attempt. You might even call it a case of reverse racism.

The Los Angeles Times has previously cataloged Cobb's plot and the repeated stumbles he's faced -- first running afoul of local health rules, then discovering on a nationally syndicated talk show that a DNA test showed he was actually 14% sub-Saharan African.

Then, over the weekend, Cobb, 62, was arrested after going on an ill-advised armed patrol of the town, population 16, with a fellow white supremacist, Kynan Dutton, 29.

Before their arrest, Cobb had texted the Bismarck Tribune about his motive: "Because of the many violences and harassments against we and the children, we have commenced armed patrols of Leith."

There's a little more to the story than that: Cobb, it seems, had felt the sting of his own brand of racial prejudice turned against him.

The local prosecutor says a fellow white supremacist had apparently targeted Cobb with racial graffiti after he'd found out that Cobb's DNA results said he was part black.
