Egyptian troops fired on supporters of ousted president Mohamed Morsi in Cairo last week. In June, anti-government protests in Turkey were broken up by what the Council of Europe deemed to be excessive force. In Brazil, weeks of demonstrations climaxed on June 21, when millions spilled onto the streets in more than 100 cities. More than 180,000 citizen-made videos captured the throngs in Brazil alone and some were uploaded to support charges of undue police violence made by Amnesty International and other civil rights groups. As amateur media grows increasingly integrated into protest coverage, software developed by researchers at the University of California at Berkeley could support and protect activists against unjust persecution. Called the “Rashomon Project,” the program synchronizes films taken from multiple angles to creating a complete timeline that could to be used as evidence of abuse during human rights trials. Ken Goldberg is professor of engineering at UC Berkeley and leader of the Rashomon Project, and he spoke with us about the project.
