North Korea may well have sunk the Cheonan, as concluded by the South Korean military-led investigative team. But meetings with some of my colleagues who have extensive experience in that part of the world, can be summarized by what one of them said to me: “The evidence presented by the LAPD in the O. J. Simpson trial was so bungled that more was needed to convict. Roughly the same is true of the South Korean military’s indictment of North Korea in the sinking of the Cheonan.”
In a meeting a week ago, a colleague compared two pictures that the investigative team used to claim:
As for conclusive evidence that can corroborate the use of a torpedo, we have collected propulsion parts, including propulsion motor with propellers and a steering section from the site of the sinking. The evidence matched in size and shape with the specifications on the drawing presented in introductory materials provided to foreign countries by North Korea for export purposes.
South Korea’s military investigators admitted Tuesday they had “mistakenly” shown the wrong blueprint of the type of North Korean torpedo they said sank a South Korean warship … The investigators called the incident a “mistake by a working-level staff.”
This colleague also shared the figure shown below and questioned (as have others) why the alleged marking on the torpedo is on a clean surface when pictures of the recovered torpedo show significant corrosion everywhere else.
These two questions are part of a larger body of issues that beg for answers . As with OJ’s trial, this is not to say that North Korea is innocent, just that a better investigation is needed before reaching a verdict that could revive the Korean war and might even lead to a nuclear disaster.
 For some of those other issues, see two of my earlier posts by clicking here and here. There is also official South Korean evidence, not covered in any of my previous posts, that its navy may have fired on a North Korean vessel prior to the sinking of the Cheonan.
