True, there were simple lapses in the investigation. The prosecution’s crucial evidence—the tape said to have contained the conversation between Shah and Chhota Shakeel—was not admitted by the court. Due to a typing error in the panchnama, the cassette mentioned in it and the one eventually presented were different. An additional three minutes in the evidence tape were not accounted for in the prosecution’s papers, and the cassette was not even sealed properly. Also, Chhota Shakeel’s voice wasn’t convincingly verified.
