I would concur that education and training for people in enforcement of justice and for people who are afraid of enforcement of justice and those in between would be essential to ensure success of this bill, that people are going to pick up the phone and call 911.
As to how to do that, across Ontario and across Canada, my personal experience is people are committed. There's a tremendous amount of human and social capital. People are willing to step up and help out. If there are resources—there's not always money—but with support from the federal government from the get-go you can deploy those resources and reach those people. Admittedly, people who are using Illegal drugs or engaging in illegal acts are a little trickier to reach, but it's not impossible.
I suspect in the U.S. it's probably an afterthought.
