We all owe a debt of gratitude to the courageous journalists who risk imprisonment, injury and death to report from repressive countries or conflict zones around the world. It is easy to take for granted the stream of information that reaches us each day from across the globe. But many people run enormous risks to bring it to us. Fourteen journalists have already been killed in the first four months of this year alone: half of them in Syria. My thoughts are with them and their families and friends. And I also pay tribute to the increasing number of “citizen journalists” who use social media to provide ground truth about what is happening in other countries, who often face pressure and intimidation.
