The face and words of the shooter:
...The suspect appears to have posted YouTube videos under the handle "Classitup10" that rail against the government and talk of revolution and terrorism. The user, identified as "Jared Lee Loughner," says in a rage-filled, rambling, and incoherent post accompanying one video:
We need a drum roll for those front runners in the election; those illegal teachers, pigs, and politicians of yours are under illegal authority of their constitution. Those dirty pigs think they know the damn year. Thirdly, tell them mother fuckers to count from 0 to whenever they feel a threat to stop their count…Those illegal military personal are able to sign into a country that they can't find with an impossible date! How did you trust your child with them fraud teachers and front runners, listener? Did you now know that the teachers, pigs, and front runners are treasonous!
In another video, the same user accuses the government of imposing "mind control and brainwash on the people by controlling grammar." Loughner continues: "You don't have to accept hte [SIC] federalist laws…A terrorist is a person who employs terror or terrorism, especially as a political weapon. If you call me a terrorist then the argument to call me a terrorist is Ad hominem."...
