Based on all the actual evidence, there's not a shred that says Palin or rhetoric or anything else contributed to this attack. The kid has had a thing for Giffords since 2007. He's an anarchist. His friend says he just wants to watch the world burn but he doesn't watch news and isn't political.

I can say with a fair degree of confidence that if Palin had never existed, this shooting still would have taken place.
