Sands Fish, a fellow at the Berkman Center for Internet and Society and a researcher at the MIT Media Lab, said that the success of #TakeItDown materialized, at least in part, because there was an organized community ready to mobilize. “Black Twitter has become an established public essentially over the past year,” he said. Currently, Fish is working with the Mapping Police Violence project to identify the link between deaths of black people at the hands of the police, and national press attention.
