There are all sorts of considerations that go into a decision such as that, including the Crown's likelihood of approving charges. It's not to say that we don't collect evidence with respect to that incident and others similar, but we do have a number of things we have to consider, including the Crown's directive with respect to their drug policy.
There are a number of considerations, some of which remain quite confidential, and I only mean that from a policing perspective. We employ all sorts of techniques, including covert ones, that we simply wouldn't talk about in a public setting.
