unreported - undocumented - tip of the iceberg -
what was most shocking for me was the lack of any concept of ethics.. Medical professionals don't get so say 'I was following orders'.

You will no doubt discuss this in a course on ethics sooner or later. Our psychiatry colleagues did very well (not the psychiatric nurse in charge) and so did the Psychological fraternity, yet I beg the answer - when do we see the damned heads rolling - charges, disciplinaries, professional council, anyone!
