If the landlord's are not able to act unless the victim falls under a 'special needs' category then they have the duty not to mislead tenants in their policy statements and agreement to the contrary.
They all claim to take asb and hate crime seriously, zero tolerance. And that should be an end to it. They have many tools available which, trust me, would be applied with zeal, should the victim retaliate in the right to self defence. I've had them conspire in entrapment, lies, denials and just about every sickening hypocracy others have endured.
The policies are couched in pc newspeak as are the staff trained to deliver Guv socialist policies under the radar. The police, the same, for they will not support a case which cannot win in court.
