In spite of the hate still being directed at Pr. G. Bush, the Tea Party movement, Sarah Palin, and conservatives in general, I don’t think the Arizona shooter was influenced by anything other than his own insanity. If the left wing kool-ade drinkers want to keep on spreading hate, I think the 1st Amendment protects their right to do so. MSNBC, the Huffington Post, and Keith Olbermann can not be held responsible for the actions of others, no matter how reprehensible their rhetoric is.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
–The 1st Amendment of the Constitution of the United States
