Do you think Sarah Palin is to partially blame for the AZ shootings because of her "crosshairs, targets"?

rhetoric she used last year? And all of the gun references, re-loading, etc? I think it's easy to blame her, but she wouldn't be legally responsible in a court of law. I think it's just a coincidence, what do you think? I think this Jared Loughner guy was just a very insane loner, with too much time on his hands, and a gun, and he was obsessed with Giffords, and just one day snapped and that is that, what do you think?
