"What is government if words have no meaning?" — the question Jared Loughner asked Gabrielle Giffords at a "Congress in Your Corner" event in 2007.

Mother Jones reports what he said to his friend Bryce Tierney: "Can you believe it, they wouldn't answer my question." Tierney says, "Ever since that, he thought she was fake, he had something against her." (By the way, 2007 is a year before Sarah Palin emerged on the national scene.)

Loughner would occasionally mention Giffords, according to Tierney: "It wasn't a day-in, day-out thing, but maybe once in a while, if Giffords did something that was ridiculous or passed some stupid law or did something stupid, he related that to people. But the thing I remember most is just that question. I don't remember him stalking her or anything." Tierney notes that Loughner did not display any specific political or ideological bent: "It wasn't like he was in a certain party or went to rallies... It's not like he'd go on political rants." But Loughner did, according to Tierney, believe that government is "fucking us over." He never heard Loughner vent about about the perils of "currency," as Loughner did on one YouTube video he created....

As Loughner and Tierney grew closer, Tierney got used to spending the first ten minutes or so of every day together arguing with Loughner's "nihilist" view of the world. "By the time he was 19 or 20, he was really fascinated with semantics and how the world is really nothing—illusion," Tierney says. Once, Tierney recalls, Loughner told him, "I'm pretty sure I've come to the conclusion that words mean nothing."...

Tierney believes that Loughner was very interested in pushing people's buttons—and that may have been why he listed Hitler's Mein Kampf as one of his favorite books on his YouTube page. (Loughner's mom is Jewish, according to Tierney.)...

Loughner believed that dreams could be a sort of alternative, Matrix-style reality, and "that when you realize you're dreaming, you can do anything, you can create anything," Tierney says....

There's a dream journal, which I'm sure we'll get to read.

... Loughner seemed ticked off by what he believed to be a pervasive authoritarianism. "The government is implying mind control and brainwash on the people by controlling grammar," he wrote in one YouTube video.....

Since hearing of the rampage, Tierney has been trying to figure out why Loughner did what he allegedly did. "More chaos, maybe," he says. "I think the reason he did it was mainly to just promote chaos. He wanted the media to freak out about this whole thing. He wanted exactly what's happening. He wants all of that." Tierney thinks that Loughner's mindset was like the Joker in the most recent Batman movie: "He fucks things up to fuck shit up, there's no rhyme or reason, he wants to watch the world burn. He probably wanted to take everyone out of their monotonous lives: 'Another Saturday, going to go get groceries'—to take people out of these norms that he thought society had trapped us in."

It sounds as though the movies were more a source of inspiration for his craziness than politics.
