The probative strength of post-offence conduct, such as concealment of weapon or flight, with or without "covering lies", will depend upon many factors including the circumstances in which the conduct occurred and the issue in proof of which the evidence is tendered. If it is open to be used by the jury for the purpose of drawing an inference as to the state of the accused's mind at the relevant time, the conduct will have to be assessed in the light of the probabilities[9]. But, because such evidence is capable of being misused by the jury, the interests of a fair trial to the accused require, as I think they required in this case, a careful direction from the trial judge of the type referred to in Edwards v. R. (supra)[10]. Such a direction should have involved a specific identification by the trial judge of the conduct being relied upon by the Crown to prove murderous intent; a direction that they could only use such conduct as proof of guilt if they were satisfied that there was no other explanation, consistent with innocence for it; and that the accused only engaged in the conduct because he knew that revelation of the truth would implicate him in the offence charged. Properly directed, the jury should also have been told that conduct such as that relied upon by the Crown could stem from reasons other than realization by the accused of his guilt of the crime charged, what those other reasons might be, and that, if they accepted that a reason of that kind was the explanation for the conduct, they should not use the evidence as probative of guilt[11].
