As you probably know, Loughner isn't talking. Supposedly, his parents told him not to. I wonder why? I wouldn't think it's because he might incriminate himself and everyone already thinks he's insane.
In any case, one of the things that is known about Loughner was that he was very concerned about the dollar not being backed by gold and becoming worthless which, according to - Glenn Beck - was going to bring about a "societal breakdown".
This was a main motive behind the Pittsburgh police killer who was very into Beck.

Pittsburgh City Paper Claim: Accused Pittsburgh cop-killer "loved Glenn Beck"
Richard Poplawski, the man accused of gunning down three Pittsburgh police officiers, was a big fan of FOX News host/right-wing cult leader Glenn Beck. Will Bunch, a contributor to Media Matters and author of the popular Philadelphia Daily News blog Attytood, has the story:
This January, I spent several days in Pittsburgh investigating the Poplawski case and seeking to learn more about what really motivated him to kill three police officers. The research was for a chapter in my book, The Backlash: Right-Wing Radicals, High-Def Hucksters and Paranoid Politics in the Age of Obama, which comes out at the end of the month. I learned quite a bit ...
"Rich, like myself, loved Glenn Beck," Poplawski's best friend Eddie Perkovic told me during a long interview in his narrow rowhouse on the steep hill running down to the Allegheny ... Perkovic and his mom -- who also had a close relationship with the accused cop-killer, still awaiting trial -- told me that for months Poplawski had been obsessed with an idea -- frequently discussed by Beck, including in ads for his sponsor Food Insurance -- of the need to stockpile food and even toilet paper for a societal breakdown. Poplawski was also convinced that paper money would become worthless -- another claim given credence by the Fox News Channel host, particularly in close connection with his frequent shilling for the now-under-investigation gold-coin peddler Goldline International.
