Re people saying SS would be involved after police seeing evidence of DV. There is an initiative called Operation Encompass which relates to this very issue. The girls' school would be informed by the police - not sure if the DV victim (usually mother) would have the option to say they didn't want this to happen. The school would then be heavily involved as it's a safeguarding issue.
I referred to another technicality cock up on a different thread - Moaning Myrtle could not have used her dead sister's ID and qualifications to get a TA job as she wouldn't have be able to get the required enhanced DBS clearance. It would obviously come back as the applicant is deceased. No DBS = no job in a school.
I know we should suspend reality to some degree, but glaring errors like this piss me off.
