Sri Lankan editor's killers still at large

About a year ago, my first entry was posted to this site, about the murder of the Sri Lankan editor Lasantha Wickramatunga on Jan. 8, 2009.   Mr. Wickramatunga had been an outspoken critic of the Sri Lankan government and his paper, the Sunday Leader,  and its staff had previously come under attack before his killing.  President Rajapaksa ordered a police investigation into his murder.  As a recent report by the International Federation of Journalists makes clear, however, to date there’s been little progress in bringing his killers to justice.  At least 14 journalists and other media workers have been killed in Sri Lanka since 2006.  Will we see anyone punished for any of these crimes?  Or will impunity continue?
