To add to Jack Cashill's post on More Tea Party Violence: The New York Times inserted this paragraph in the middle of a story about the mass murderer who killed 6 people and wounded 18, including Congresswoman Gabrielle Giffords:

During the fall campaign, Sarah Palin, the former Republican vice-presidential candidate, posted a controversial map on her Facebook page depicting spots where Democrats were running for re-election; those Democrats were noted by crosshairs symbols like those seen through the scope of a gun. Ms. Giffords was among those on Ms. Palin's map.
