Here's another intriguing angle to this story... I really don't want to link to that vile site GLP, so instead I'll just summarise an interesting post I noticed over there hinting at a mind control angle.
Susan Hileman brought her 9-year-old neighbour Christina Taylor Green to Rep. Giffords' event. We all know Taylor Green sadly was killed and Hileman was injured. Cornell University issued a press release stating:
Susan Hileman '73, a graduate of the College of Human Ecology, was shot three times by the gunman who also wounded U.S. Rep. Gabrielle Giffords Jan. 8 in Tucson, Ariz. Six people were killed and 14 people were wounded in the shooting. Hileman is in stable condition and is expected to recover... Hileman is married to William Hileman '72, a graduate of the College of Arts and Sciences. She is a retired social worker who maintains close ties to Cornell as chair and director of the Cornell Alumni Admissions Ambassador Network for the Cornell Club of Southern Arizona and as a member of the Human Ecology Alumni Association Board. She also served on her class's 30th Reunion Campaign Major Gifts Committee (2002-03).
http://www.news.cornell.edu/stories/Jan11/Hileman.htmlSaid poster at said vile site looked into Cornell's 'College of Human Ecology' and found its origins rooted in a joint research project with the CIA that studied "how a man can be made to think, 'feel,' and behave according to the wishes of other men, and, conversely, how a man can avoid being influenced in this manner."
