How has the accused obtained copies of statements of witnesses from the police?

British Columbia, Canada

The following excerpt is from R. v. Anderson, 2000 BCPC 159 (CanLII):

The accused has copies of statements of these witnesses. These were obtained from the Crown. Again, an example of the effectiveness of Regina v. Stinchcombe. Therefore, the accused knows what the witnesses told the police and he could ask them what they know when he places them on the witness stand before me. That evidence would be relevant on the evidence of sufficiency.
