I have a 20-second intervention here.
As I've stated in several fora in recent days, one of the issues with gun violence is that this is a multivariate problem, precisely because we've reintroduced discretion into a process that previously had a mandatory 10-year minimum sentence. There's good evidence both in Canada and abroad from the data, not my point of view, but from the research that we have, that mandatory minimum sentences impose a serious deterrent on this type of violence.
There is evidence that there might be situations where discretion is probably not the best way to achieve the outcomes for public safety that we're looking for.
