It was far from a perfect crime and far from a perfect coverup: a shooting in broad daylight, hundreds of witnesses, scores of video cameras recording the crime from many angles, audio recordings of the shots fired, clear photos of a man brandishing a murder weapon, an insignia identifying the suspect's place of work, and an autopsy analysis of a body with clear gunshot wounds.

Do we have an arrest and prosecution? No. We have a one-page fax that doesn't give the name of a suspect, and doesn't even recognize that a crime was committed. This is the blind and mute world of Japan-Myanmar diplomacy.

Myanmar Deputy Foreign Minister Maung Myint recently sent a three-sentence letter to the Japanese Ministry of Foreign Affairs (MOFA), addressed to the family of Kenji Nagai, the journalist whose murder in Yangon had been telecast around the world. The scene of him on the ground with a mortal wound, still trying to film while a military goon faced him with a rifle, is not easy to forget. For me it may be impossible because I once met Nagai and was impressed by his journalistic dedication and courage.
