Since all those isolated incidents involving terroristic violence directed at "liberals" and the "government" keep adding up into a serious trend, we've decided it's time to start keeping systematic track of the problem -- especially because mainstream media seem intent on refusing to recognize the trend.

Here's the text for the 20 23 24 events we've enumerated so far:

-- July 2008: A gunman named Jim David Adkisson, agitated at how "liberals" are "destroying America," walks into a Unitarian Church and opens fire, killing two churchgoers and wounding four others.

-- October 2008: Two neo-Nazis are arrested in Tennessee in a plot to murder dozens of African-Americans, culminating in the assassination of President Obama.

-- December 2008: A pair of "Patriot" movement radicals -- the father-son team of Bruce and Joshua Turnidge, who wanted "to attack the political infrastructure" -- threaten a bank in Woodburn, Oregon, with a bomb in the hopes of extorting money that would end their financial difficulties, for which they blamed the government. Instead, the bomb goes off and kills two police officers. The men eventually are convicted and sentenced to death for the crime.

-- December 2008: In Belfast, Maine, police discover the makings of a nuclear "dirty bomb" in the basement of a white supremacist shot dead by his wife. The man, who was independently wealthy, reportedly was agitated about the election of President Obama and was crafting a plan to set off the bomb.

-- April 2009: A white supremacist named Richard Poplawski opens fire on three Pittsburgh police officers who come to his house on a domestic-violence call and kills all three, because he believed President Obama intended to take away the guns of white citizens like himself. Poplawski is currently awaiting trial.

-- April 2009: Another gunman in Okaloosa County, Florida, similarly fearful of Obama's purported gun-grabbing plans, kills two deputies when they come to arrest him in a domestic-violence matter, then is killed himself in a shootout with police.

We'll update as the incidents occur. Also, readers should feel free to contribute potential additions. Remember, these incidents involve more than simple threats or assaults but rather constitute incidents of actual domestic terrorism.
