US Rep. Gabrielle Giffords (D) was just shot in Arizona. Is this a direct result of the hate speech in the recent campaigns?

The great majority of talk radio is dominated by some real nutcases like Glenn Beck and Rush Limbaugh. Sarah Palin, had Giffords in her“crosshairs” as a targeted district. Is this just the tip of the iceberg for an armed rightwing insurrection? I fully expect one or both of them to say something like “I don’t condone the shooting, but I understand it”.

I also expect the congress to run scared step up their personal security, maybe even adding restrictions in Washington, D.C. It could be a good thing if lobbyists were restricted from access to the capitol
