The lone wolves have emerged
Last spring, conservatives were in an uproar over a Department of Homeland Security report that warned homegrown, right-wing extremists could commit terrorist acts within the United States. Nearly a year later, that report appears to have been very prescient.
The report, "Rightwing Extremism: Current Economic and Political Climate Fueling Resurgence in Radicalization and Recruitment," particularly identified "lone wolves" as potential dangers.
Conservatives wailed that the report unfairly singled them out. The more conspiratorial-minded saw it as justification for a government crackdown on dissent.
In retrospect, they had nothing to fear. If anything, the right wing today is more vocal than it has been in a generation, thanks to the Tea Parties.
Yet DHS was right. Since last spring, there have been several lone wolves fueled by racism and anti-government ideology.
In Pittsburgh, a gunman killed three police officers.
In Washington, a white supremacist killed a guard at the Holocaust Museum.
In Austin this week, a man whose anti-tax, anti-government views dated back decades, flew a plane into Internal Revenue Service offices.
Even Southwest Virginia felt the sting when a gunman in December took hostages at the Wytheville Post Office.
Someone owes DHS an apology.
