I read a very interesting article regarding the divided opinions on the sinking of the Cheonan ship.
Here are some points from the piece:
On the conflicting views of the incident - The types of evidence presented by the two groups also differ entirely in character. The former group has presented evidence that any sensible person could understand, including the clean condition of the surviving and deceased sailors, the lack of a water column, the damage state of the ship’s screws’ wing blades, and the fishing net wrapped around the propeller’s axis. On the other hand, the latter group has presented a piece of torpedo propeller.
The torpedo age – Regarding the degree of corrosion of the metal surface, Lee Jong-in conducted his own experiment with small metal pieces under water, and argued that the JIG’s claim that the chunk of the metal had been underwater for just 50 days was false. This is consistent with the results of visual examination done by Russian experts.
The markings on the torpedo-the “No. 1” mark could be written by South Koreans as well, and thus it would not be taken as evidence by a court of a democratic society. Even the JIG have denied its evidentiary validity; their own chemical analysis concluded that the ingredient of the blue ink was “Solvent Blue 5” that had patented by a South Korean company, Monami, and they said that it cannot be traced to the North Korea.
Markings on the torpedo and the fragments on the propeller-Song’s claims contradict the JIG’s claim that the “adsorbed materials” are aluminum oxide stuck to the propeller as a result of the explosion. Moreover, the JIG claimed that the paint on the exterior of the torpedo burned away completely due to the heat, and Dr. Song’s conclusion predicts the exactly opposite.
Accusation of fabrication-However, a quick examination by Dr. Panseok Yang, a specialist in EDS, and myself, a specialist in XRD, revealed that the JIG’s data did not make sense, and that some of the data must have been fabricated.
Conclusion -During the course of the Cheonan issue, South Korean society has been showing an outstanding collective reasoning. Why, then, have we so far been unable to unveil the truth about the sinking? The reason is that the South Korean government is hiding the relevant information. A formal congressional inquiry is needed, but the current congress is neglecting its own proper duties. Even with the limited information, however, cracks are showing.
