It is not surprising that the Wikipedia entry for the phrase would be tampered with. After all, the site prides itself on being an openly-edited medium. If anything, it would have been surprising if someone hadn’t placed Palin’s picture on the page.
For those of you who may not understand the connection between Sarah Palin and the term "blood libel," you may want to turn your attention to a speech she recorded and presented to the internet on Wednesday, entitled “America’s Enduring Strength." In it she attempted to distance herself from any blame placed on her for the shootings at the public meeting held by Rep. Giffords in Arizona over the weekend.
Unfortunately for Palin, instead of helping her public image, the blood libel speech further sealed her reputation for unintentional tactlessness.
So, given the nature of Wikipedia, which surprises you more: that the blood libel page was hacked in the first place, or that someone removed Sarah Palin’s picture from it so soon?US News paper
