This is why we can't have nice things in this country. It's always comes down to some rhetorical discussion about edge cases and possibilities of how a tiny fraction of people might be negatively impacted, so let's not do it.
Let's frame it this way, "Is it humane to allow people be a slave to their mental illness and living on the streets?" The answer is clearly, "no". Allowing the mentally ill to live on the streets betters no ones life and causes many issues for everyone. If people with a mental health issue can not or will not take care of themselves, then someone else has to do it (IE: The Government).
It is humane for everyone if the mentally ill are forced to get treatment or confined if they refuse it.
