Ever since Harvard Forum II, Randy Spence and I have been kicking around Amartya Sen’s notion that ICTs have a net positive liberating potential. I have been the skeptic. But evidence is adding up in Randy’s column: For some of the protesters facing Bahrain’s heavily armed security forces in and around Pearl Square in Manama, the most powerful weapon against shotguns and tear gas has been the tiny camera inside their cellphones. By uploading images of this week’s violence in Manama, the capital, to Web sites like YouTube and yFrog, and then sharing them on Facebook and Twitter, the protesters upstaged government accounts and drew worldwide attention to their demands. A novelty less than a decade ago, the cellphone camera has become a vital tool to document the government response to the unrest that has spread through the Middle East and North Africa.
