Selective investigation

The CIB maintained that the Bureau put investigation of the March 19 incident at the highest priority. Yet it never pursued the following evidence that may incriminate President Chen.

• The CIB did not investigate whether bullets can burn skin or melt polyester fibers.

• The CIB did not investigate whether a 1 cm long bullet can produce an 11 cm long and 1-2 cm deep graze wound.

• The CIB did not investigate whether a 1 cm long bullet can produce a 2.4 cm long hole on Chen's shirt.

• The CIB did not investigate whether a round nosed bullet can penetrate Chen's undershirt on exit without perforating Chen's shirt made from weaker fabrics.

• The CIB chose to exclude, from its forensic report [CIB1], the sizes of all bullet holes on Chen's clothing, as well as the distance between the two bullet holes on Chen's T-shirt.

• The CIB did not investigate the consistency of the length of Chen's wound (11 cm) and the distance between the two bullet holes on Chen's T-shirt (9 cm).
