This has happened so often (much too often) and we know the problem and the solution: police in North America are poorly trained to deal with mentally ill people. So why aren't they getting better training? Why aren't police departments changing? At this point, there definitely is blame to allocate and it lies solidly with Canadian police departments. Compare what they do with what is standard procedure in Britain. By comparison, the police here are jackboot thugs. Improve the training! Stop murdering sick people! Stop making excuses.
