``No powder residue was detected on the three entrance holes, on the jacket, the shirt and the undershirt. The black marks on the entrance holes were caused by burning, resulting from penetration by the high speed lead bullet.''See page A4 of Chinatimes Express, March 23, 2004.64The last sentence in the CIB announcement quoted above, that the black marks on the bullet holes were caused by the bullet which burned the fabrics, was clearly wrong; see §4.65
There is no evidence as to whether the CIB possessed the knowledge that bullets do not burn skin. We do know that, at least one of their forensic experts thought that bullets can burn the clothing, a basic error. There are two possibilities; neither will enhance CIB's credibility. Suppose that the CIB did not know this well-documented fact. That would make the CIB an incredibly incompetent agency. If the CIB does not even know such a basic fact with regard to gunshot wounds, then one cannot possibly trust its investigation and the report it subsequently produced.66The other possibility is that the CIB knew the fact that bullets never burn the skin, but still chose to claimed that Chen suffered a gunshot wound.
