This is reportedly the MySpace of Jared Loughner, the 22-year old kid who shot Congresswoman Gabrielle Giffords, wounded 12 and killed 6, including a federal judge today. It's unsettling to see the kid's placement of violence against a US History textbook.
The MySpace page has since been taken down but his picture in the profile does match his description (which is admittedly general), "a young white man who looked like a "fringe character," in his mid-to-late 20s, clean-shaven with short hair."
His purported Youtube account is also eerie and littered with videos such as this one, which express some of his beliefs and anti-governmental stance:
It's obviously not a reach to say Loughner is sick and twisted—he did selfishly ruin lives and deeply altered families—his online presence goes to show that his troubled thoughts occurred long before today.
