Washington Post writer Dana Milbank says while you can't specifically link course public discourse to the Tucson shootings, you can make a generalized connection.

...I think it's a bit of a straw man, that people are claiming that, you know, Beck and Palin are being blamed. Mostly, people are saying they're not being blamed for this particular incident. They are being blamed, as well as some on the left should be blamed, for inciting people generally.
