To pick up on what BTR was saying.
RLC have a problem if they involve themselves. It is no longer an 'everyday' situation.
There is no fly on the wall to stop the daily occurences of any sort of violence in 'real life',other than the police.
They are damned if they do & damned if they don't.
However they probably do have a duty of care to the residents,unless the residents have waived those rights.
But surely if they monitor the cams & if they see something like the incident today, they could contact the apartment or individual(s) involved via telephone,email or whatever, to ask if everything is ok?
