Yes, and I think the best way to do that is to have them not attend at all, but that's not what this bill is about. Absolutely, there are nightmare stories coming out of the U.S. about police arresting people at scenes where good Samaritan legislation is in place. The U.S. legislation is varied in terms of how many offences are included. Some include more than others, so it's a bit of a dog's breakfast across the country. There is no evaluation.
The only data I'm aware of is a study out of Australia that evaluated police non-attendance at overdoses, and they attributed a 7% decrease in overdose deaths to that police policy.
