If at the end of the 3-month period it is considered likely that detention criteria are still fulfilled, new recommendations MII and MIII are filed and the renewed detention is then valid for 6 months. However, this second period of detention has to be immediately confirmed by a local administrative court.
That's one part of the solution; whether it works is left as an exercise to the reader ..
Wow, now that is something I have not heard at all despite how frequently I've heard about the Finland housing first approach to drug addiction/homelessness. Thank you for the reading topic!
EDIT: Where did you get these numbers and what kind of detention do they refer to? I am not finding this 214/100k number anywhere. The prisoner population in Finland seems to be about 50/100k and the pre-trial detention rate is similar (unlike where I live where pre-trial accounts for 80% of detainees due to slow courts)
EDIT 2: Nevermind, I did find psychiatric holds, which I see to be reported as 150/100k which is certainly much much higher than other countries.
If you're concerned about abuses of this kind of arrangement, look for example to the Soviet Union, where a person who was against the government was of course mentally ill and put away – because how can you be against the wonderful government?
Okay, but this thread is about homeless housing.
I have known a few paranoid schizophrenic people in my life. They needed help, but refused all attempts to get it to them. One eventually did get help - but only because he committed a felony and his condition was obvious enough that the court forced an insanity plea on him.
While the above sounds awful, it could be worse. The US used to have a lot of institutions and force people into them all the time. Abuse was common - it is debatable if freezing to death on the streets is worse than the institutions of old - most homeless don't freeze to death (though it happens). The right answer is reform the institutions, but I don't know how you do that.
Homeless who are mentally ill -> Forcefully put into institutions
Homeless who are drug addicts -> Forcefully put into institutions
Homeless who are criminals -> Forcefully put into jail or prison
How many homeless do you have left after that? The majority of homeless people in any place in the world has one or more of the above problems. Why would anybody be homeless if they didn't? Except for a short time during a crisis.
