That psycho Loughner, was following Giffords since 2007.
Regardless of what you think of Palin it had nothing to do with her.
Loughner attended one of Giffords rallies in 2007 in which he asked her a question and didnt like one of her answers. He fixated on this poor woman ever since.
It is very unfortunate. Giffords seems like a true role model human being and an example for the rest of us.
