In the aftermath of the Tucson shootings, the contention of the left that heated rhetoric on the right and on the part of Sarah Palin in particular is somehow a root cause of this tragedy is, to say the least, disingenuous.
Sheriff Dupnik in particular deserves to be singled out for scorn in this regard. A review of the available evidence shows that not only was jared Loughner not a right-wing nut, but apparently paid little attention to politics at all. The only voices that seem to have affected his behavior were those coming from his fillings, or perhaps his breakfast cereal.
