Loughner's records released
The Pima County sheriff's office and the campus police at Pima County Community College have released their records on the shooter. Allahpundit has the details. Summary: No real red flags in his interactions with local police, some red flags in his interactions with campus police, and lots of red flags in the testimony of those who knew him. The friends' stories paint a picture of a man succumbing to paranoid schizophrenia.
In other words, not an "extremist" in any political sense whatsoever. To further push the meme that he was politically motivated, is to knowingly push a lie. Not that that has slowed anyone down so far.
