Non is torn.
About have the cases that cross my desk stem from health related issues, either mental illness or addiction. I'd like it if we had health-care resources/facilities that my clients could take advantage of as opposed to jail or the department of corrections. To that end I think we need to maybe look into a sanitarium 2.0 program.
However I can see your fears about abuse. In Minnesota they had a contested hearing like a mini-trial prior to commitment and in Colorado (who's mental-health laws are a f**k) most people never get beyond the 72 hour hold.
Any system, even one with reasonable legal-safe guards, is going to be abused.
