There's nothing in this clip to indicate negligence on the part of the hospital or its staff. If the medical staff checked the patient and found him dead, what were they supposed to do? When a person dies body temperature doesn't 'evaporate" instataneously. It takes hours for rigour mortis to set in.
What's more, you can't condemn a hospital on the basis of a clip posted by an emotional son who has just lost his father. It is very subjective.
Lastly, Kenyan bonobos must realise we are in era of Covid. Most hospitals don't have ICU space so even if this man was alive the best was to refer him elsewhere.
