Before he allegedly went off on his shooting rampage in Tucson, Jared Loughner listed some of his favorite books on his YouTube page. These included: “Animal Farm,” “Brave New World,” “Alice in Wonderland,” “One Flew Over the Cuckoo’s Nest,” “Through the Looking Glass” and “The Communist Manifesto.” Many of these books share a common theme: individuals trying to control their own thoughts and government or some other force trying to take that control away.

Loughner also made a series of videos. These, too, suggest that he was struggling to control his own mind. Just before his killing spree, Loughner made one called “My Final Thoughts.” In it he writes about different levels of consciousness and dreaming. He tries to build a rigid structure to organize his thinking. He uses the word “currency” as a metaphor for an inner language to make sense of the world.

“You create and distribute your new currency, listener?” the video asks. “You don’t allow the government to control your grammar structure, listener?”

All of this evidence, which is easily accessible on the Internet, points to the possibility that Loughner may be suffering from a mental illness like schizophrenia. The vast majority of schizophrenics are not violent, and those that receive treatment are not violent. But as Dr. E. Fuller Torrey, a research psychiatrist, writes in his book, “The Insanity Offense,” about 1 percent of the seriously mentally ill (or about 40,000 individuals) are violent. They account for about half the rampage murders in the United States.
