It is possible for all of those things, but they all require a sacrifice from the public for the public good, be it in tax income, re-thinking policing in general, as well as its involvements mental health care, and accepting that people of mixed privileges need to co-exist (shelters in all types of neighbourhoods).Perhaps the exchange above has run its course.
It is possible to dislike the presence of encampments and acknowledge the danger they pose to the residents of same; while equally admitting they exist, at least in part, because there aren't enough shelter beds; and because some of those beds
are in unreasonable conditions which are neither safe nor hygienic.
It is possible to agree that upon providing an indoor place people can go, which is both safe and hygienic, it is then reasonable to ask people to take up that opportunity and move along from encampments/parks.
It should also be possible to agree that for reasons both of compassion and self-interest (I want my park back) that this issue should be addressed with all due haste.
Shouting that a problem exists and "make it go away" isn't the same as wanting change. It's demanding status quo.
