It's a tough one. We had a drunk living in our block of flats for a while. To get a flat in our block you need references, but his family faked the references for him as they couldn't deal with having him living with them any more. Which I'm sure was great, but equally, the other residents of the flats which included two single elderly retired people, a young girl with a baby, a couple of single female night-shift-workers and me who is young, female, disabled and living alone... we couldn't really deal with this alcoholic and his friends causing havoc. Human vomit and excrement smeared all over the shared hallways, and then they would bash at our doors asking us for help. We simply couldn't live with it. The landlord tried to get the police involved, they said they'd done all they could with him unless he actually physically assaulted someone. And he was loath to evict the guy because Social Services didn't really want to pick up the pieces either. Where should someone in this state go?
