Iirc the Victorian government in Australia decided to buy individual apartments in high rises to put drug addicts in resulting in the buildings becoming so unsafe that the original occupants had to sell and move somewhere else. Turning them in to radical anti public housing activists so they don’t have to move and lose a load of money again.

Yeah, the problem here is that leaving syringes on the floor, urinating in flower beds and talking shit is insufficient to arrest the person. But is sufficient to drive a lot of tenants away from the house.
