@hawkeye10,
Then you're the police state adovcate.
The mentally ill are entitled to the same civil rights, and civil protections, as everyone else.
Refusing psychiatric treatment is no worse, or more self-destructive, than people who chose to smoke cigarettes, or drink excessively, or eat their way into obesity, or lots of other things that people do that aren't in their best self-interest.
Most mentally ill people are not homeless and living on the streets. Most live at home, others are in group homes or independent living programs. If they are more "invisible" now, it's because they now better blend in with their communities, and they are able to live fuller and less restricted lives.
