I did. The main zero-tolerance policy referred to in the article is someone getting into a fight with staff and roommates at a social care facility.
You condemn that policy, so I suppose you think this should be tolerated to a degree?
Let's say that a homeless shelter abolished it's zero-tolerance policy. Staff and other occupants can now be assaulted a few times, before someone gets kicked out.
Who'd work at this facility? At this point, you aren't looking for social workers, you're looking for prison guards. They'd treat their charges with the same love and compassion that correctional officers are known for.
Who'd go into this facility? Would a non-violent peaceful person even want to be sheltered there?
Do you really think a facility like that will help anyone?
Suddenly a zero-tolerance policy towards violence isn't such a bad idea, is it? Maybe, just maybe there is no orphan crushing machine, is there?
