I'm a medico and unfortunately I have learnt to temper my training/natural inclination with pragmatism whenever I am out of my normal working environment. Sometimes it is not strictly the law that applies.
I recount a story from an American surgeon (obstetrician) who, after rendering assistance, reached his middle east destination. His passport was confiscated at immigration, led into an interrogation area, refused contact with the outside world, and curiously could not find an English speaking person to communicate with. After several uncomfortable hours, the penny dropped when he was asked about his medical credentials. It appeared the person he treated is a relative of a connected family. He was then released, finished his conference, and left the country vowing never to return. When describing the clinical management, I can't see where any problem was - we assume it was either personality clash, social mores broken unknowingly, who knows (admittedly the story is only from his perspective).
No laws broken. No charges laid. No official case law or medical write up, just anedoctal.
Just to be clear - obstetricians are NOT surgeons!
