U.S. Representative Gabrielle Giffords (D-AZ), 40, was shot in the head at close range at a public event in front of a Safeway store in northwest Tucson. Giffords was one of 20 House Democrats Sarah Palin targeted last March on her Facebook page in response to their votes for health care reform. At that time, Palin posted a map of the United States with gunsight-style crosshairs superimposed over the districts of Democratic House members who had voted in favor of the health reform bill. Around that same time, a wave of threats and intimidation was ongoing against members of Congress which led Capitol Police to meet with lawmakers and advise them about taking precautions to protect their personal security. In one of the more alarming incidents, Giffords' office window was smashed on the night of the health care vote. In June, Nevada senatorial candidate Sharron Angle advocated use of "second amendment remedies" if voters fail to get their way at the ballot box.
