Tuscon killings

The attempted assassination of US House Rep. Gabrielle Giffords and the murder of 6 people in the group is a depressing topic about which there doesn't seem to be much useful to say, beyond what Gail Collins says about the inexplicable fixation of the gun lobby of ensuring easy access to semi-automatic weapons (as opposed to plain old single round pistols).   But in the particularly idiotic talking points revolving around the relative significance of Mein Kampf and The Communist Manifesto in Jared Loughner's reading list, it's strange that there's not more attention on the presence in that list of The Wizard of Oz, since it may confirm his obsession with the foundations of currency.
