Q

What is important for jurors to keep in mind about circumstantial evidence, as set out in R. v. Villaroman?

A

The issue is whether guilt is the only reasonable inference, not the strongest reasonable inference to be drawn from the circumstantial evidence. An accused is entitled to an acquittal if there are reasonable inferences other than guilt, even if such alternative inferences are not as strong or compelling as an inference of guilt
