A sign-language interpreter on Ukranian state television helped oust Yanukovych when she added commentary to her "translation" of the news to the effect that the election had been rigged:
During the tense days of Ukraine's presidential elections last year, Dmytruk staged a silent but bold protest, informing deaf Ukrainians that official results from the Nov. 21 runoff were fraudulent.
Her act of courage further emboldened protests that grew until a new election was held and the opposition candidate, Viktor Yushchenko, was declared the winner.
(Thanks, Bram!)
