WASHINGTON — In 2000, I had the privilege to present Lasantha Wickramatunga, from Sri Lanka, with the Transparency International annual Integrity Award. Wickramatunga was a prominent and tenacious newspaperman with the courage to ask tough questions, call for government accountability and expose corruption. On Jan. 8, 2009, he was driving to work when eight unidentified gunmen on motorcycles shot him in the head, the BBC reported. He died soon afterward. He was 52.
