Officials see rise in militia groups across U.S.

Militia groups with gripes against the government are regrouping across the country and could grow rapidly, according to an organization that tracks such trends.

The stress of a poor economy and a liberal administration led by a black president are among the causes for the recent rise, the report from the Southern Poverty Law Center says. Conspiracy theories about a secret Mexican plan to reclaim the Southwest are also growing amid the public debate about illegal immigration.

Bart McEntire, a special agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives, told SPLC researchers that this is the most growth he's seen in more than a decade.

"All it's lacking is a spark," McEntire said in the report.

Last October, someone from the Ohio Militia posted a recruiting video on YouTube, billed as a "wake-up call" for America. It's been viewed more than 60,000 times.

"Things are bad, things are real bad, and it's going to be a lot worse," said the man on the video, who did not give his name. "Our country is in peril."

The man is holding an AR-15 semiautomatic rifle, and he encourages viewers to buy one.

While anti-government sentiment has been on the rise over the last two years, there aren't as many threats and violent acts at this point as there were in the 1990s, according to the report. That movement bore the likes of Timothy McVeigh, who in 1995 blew up a federal building in Oklahoma City and killed 168 people.
