A civilized society would force them off the streets and into involuntary recovery centers rather than letting them rot on streets while committing crimes and harassing citizens.
Agreed. If someone collapsed and fell unconscious in the street, EMTs would take that person to a hospital.
No one would ask permission first: “May we save you? May we take you to a hospital?”
If someone were standing on a ledge, ready to jump, rescue workers would stop that person from committing suicide.
If someone were a public nuisance causing a disturbance, police would arrest that person.
Yet, every day, people with drug addictions are free to do all those things in the streets, and no one is stopping them.
