(CNN) -- Supporters of Ferguson, Missouri, Police Officer Darren Wilson say they have faced threats over their views, but vowed not to be silenced. An unnamed spokeswoman for the Support Darren Wilson group, speaking at a rally Saturday, accused the media of having a bias against supporters of the officer. "We believe this has only intensified the destruction of the community of Ferguson and the surrounding St. Louis areas," said the spokeswoman. "We will not hide. We will no longer live in fear," she said. "We ask this question: Can justice ever be attained if one side's supporters are living in fear of speaking out?" The online fund-raising effort for Wilson surpassed $300,000 on Saturday, according to totals from two related pages on GoFundMe.com.
