I get that. But I also understand Jahryn’s points. There are people who simply will avoid anyplace with a police presence.
No reason to not service the people who won't.
That is true. But having a police presence in effect denies services to those who feel unsafe around police.
I don't think that there is any one size fits all type of shelter for those who do not have homes. Some people end up without shelter because of bad behavior or law breaking and for others, it is merely a matter of bad luck: too many bad turns, maybe only one bad turn of luck can remove what little security they have. I was once close to that myself, years ago.
Some spaces need to be able to house families, some need to house single people, people with dogs or cats, people with mental health issues, other health issues, disabilities, addictions, etc. Different levels of crisis management are needed and different types. Job training, secure place to sleep, eat, shower, receive mail. Maybe even receive visitors. Ideally most such shelters would really be small communities that include health care, job training, therapy, childcare, various types of education, mostly geared towards the practical but also, don't we all need a bit of art and music in our lives? The space to be able to create and share? Social workers, mental health and addiction counselors on site as close to 24/7 as possible. Police only where necessary.
