Mr Ng submits that the telephone conversation incriminates Agbozo and that Agbozo had tried to cover that up by lying to the CNB officers on the content of the telephone conversation. PW14, PW16 and PW20 gave evidence that after the telephone conversation with the unknown caller ended, Agbozo informed them in English that the unknown caller asked him why he did not answer the call from “Frank” (another name for “Fred”), and that he had replied to the unknown caller that he was busy with checking-in at the Singapore airport. The unknown caller reportedly then told Agbozo that “Frank” would call Agbozo later. Based on the English translation of the recorded telephone conversation, this was not what Agbozo had in fact said to the unknown caller. Agbozo maintains that he did not lie to the CNB officers, and says that he had asked the unknown caller where the person who he was supposed to give the “thing” to was because the officers had specifically instructed him to ask this question. PW16 and PW20 deny ever giving such instruction to Agbozo. It is not disputed that Agbozo knew that his telephone conversation was being recorded, and so Agbozo says that he would not have said anything incriminating in the telephone conversation unless he was specifically instructed to do so by the CNB officers. In response, Mr Ng submits that a person who is arrested may not always act rationally. In evaluating evidence, the court is entitled to assume that people act rationally as ordinary persons in their positions are expected to act, unless the contrary is proved. A person in Agbozo’s position who knew that the telephone conversation would be recorded is unlikely to voluntarily make statements that incriminate himself. However, in the present case, I do not believe Agbozo’s testimony that he was specifically instructed by the CNB officers to ask the unknown caller who the person he was supposed to pass the “thing” to was; if this is true, Agbozo should have mentioned it when he was later given the chance to do so when he was recording his statements to the CNB. Yet, he did not do so. In his statement recorded on 13 April 2013, he merely said that the unknown caller had asked him where he was and on learning that he was at the Singapore airport, said that he (the unknown caller) would inform “Fred”. Although Agbozo knew that his telephone conversation was being recorded, he might not have expected that the conversation would be translated, as he had spoken mainly in Twi which is a language that very few people in Singapore can understand. Nonetheless, I am of the view that the telephone conversation is, on its own, insufficient to prove, beyond a reasonable doubt, that Agbozo had actual knowledge that methamphetamine was hidden in the haversack and suitcase. At best, the telephone conversation only shows that Agbozo knew that he was supposed to pass a certain “thing” to someone in Singapore, but it is not clear that this “thing” was methamphetamine.
