Oberlin College in Ohio suspended classes this week after a student reported seeing someone dressed in Ku Klux Klan robes. It follows a string of recent hate incidents on campus.
Last August, a 40-year-old ex-soldier-turned white supremacist rocker shot up a Sikh temple in Oak Creek, Wisconsin, killing six people.
And a few weeks later, a group of Georgia men was linked to an anti-government plot to assassinate President Obama.
It's all part of what the Southern Poverty Law Center says is a disturbing trend. The group's new study says the number of anti-government groups is at an all-time high - many driven by their fear that the government will strip them of their rights.

Outfront tonight: Mark Potok is the author of the report and a senior fellow at the Southern Poverty Law Center. Michael Medved is a conservative commentator for Salem Radio and John Avlon is a CNN contributor and author of "Wingnuts: How the Lunatic Fringe is Hijacking America."
