An elderly fanatic shoots dead a black security guard at the museum in Washington DC where America commemorates the Nazis attempt to wipe out the Jews of Europe.
A week earlier, thousands of miles away in Wichita, Kansas, another lone gunman enters a crowded church and shoots dead Dr George Tiller, who ran a busy abortion clinic.
Within hours of the latest attack, blogs and social networking sites are buzzing with talk that the two incidents taken together confirm the rise of right-wing extremism in America.
On the left there is a strong belief that the attacks confirm a report prepared by the Department of Homeland Security earlier in the year which warned that the current political and economic circumstances in the US were creating a hothouse atmosphere within which right-wing extremism would flourish.
Those political circumstances, of course, include the election of America's first black President, Barack Obama - an event greeted with rage and horror on the extreme right.
