If you have informed knowledge of care homes then you would absolutely know there are several legal channels and needed safeguarding requirements that mean not every resident can just be released on the whim of their family. Believe me I guarantee in the 20 years I've worked in social care I have more experience than you in these situations. I could give you dozens of experiences where someone on paper looks like they can care for a family member and it has ended horribly , abuse and neglect. There are checks and balances for a reason.
Honestly how dare you wrap this up as you being so very concerned and knowing the real story. OP have you sat with a crying 82 year old who desperately wants to go home but you know they are in the home because their daughter had a breakdown with the understandable stress of caring for a family member and left her alone to the point of near death , causing social services to attend ? Because I have , and you can't tell a scared desperate woman that so you hold her hand , you keep her calm until she feels up to going into another room. Then you do that 30 minutes later because she has forgotten again.
Then another 30 minutes later.
I've had multiple family members "claim " they are capable and where I've had to attend safeguarding afterwards, read court transcripts.
Care is a complex and legally loaded situation where the majority (not all I accept) of professionals work their backside off to do the right thing.
You honestly think waltzing on and giving a half assed version of this to make yourself seem caring is ok? Oh and not to mention that you would happily assault an often exhausted stressed care worker if they were trying to enforce rules. Beautiful. You seriously need to consider your view on this.
I would be extremely surprised if there wasn't an issue here where SS had blocked home for safety reasons.
Come back and witter on when you have any concept of the complexities of care in residential settings or in the home.
