The intent behind the people setting up the program is besides the point; if the actual cops think your behavior is suspicious, are they prevented from investigating? If not, then the increased interaction caused by this program can very well lead to more situations wherein you aren't free to say no.

"Information about people believed to be “at risk” of becoming criminals or victims of harm is shared between civilian agencies and police and is added to the database when a person is being evaluated for a rapid intervention intended to lower their risk levels. Interventions can range from a door knock and a chat to forced hospitalization or arrest."

That makes sense I guess, thanks!
