THE DHS REPORT WAS ON TO SOMETHING

Right-wing extremists have become energized by the election of Pres. Obama and this is a pattern we've seen before, according to Christina Page in HuffPo:

In March 1993, three months into the administration of our first pro-choice president, Bill Clinton, abortion provider Dr. David Gunn was murdered in Pensacola, Florida. That was the beginning of what would become a five-fold increase in violence against abortion providers throughout the Clinton years.

Scott Roeder, the murderer of Dr. Tiller, was also a right-wing extremist, according to this report from McClatchy:

Roeder, who in the 1990s was a manufacturing assemblyman, also was involved in the "Freemen" movement. "Freemen" was a term adopted by those who claimed sovereignty from government jurisdiction and operated under their own legal system, which they called common-law courts. Adherents declared themselves exempt from laws, regulations and taxes and often filed liens against judges, prosecutors and others, claiming that money was owed to them as compensation. ... In April 1996, Roeder was arrested in Topeka after Shawnee County sheriff's deputies stopped him for not having a proper license plate. ... Roeder, who then lived in Silver Lake, Kan., was stopped because he had an improper license plate that read "Sovereign private property. Immunity declared by law. Non-commercial American.'' Authorities said the plate was typical of those used by Freemen.

This sort of secessionist thinking is promoted by right-wing talk radio.
