@BillRM,
Have you ever tried getting to sleep with things attached to your body to detect whether you have carked it? And MJ wasn't about to have agency nursing staff in and out of his bedroom when nobody at all was allowed in his bathroom. And he probably expected Dr Murray to be on hand during the day.
I feel certain that Dr Murray was doing his best for that particular patient in those circumstances which were unique. He is on the record as a highly thought of doctor of the poor. The patient was not only nuts but desperate as well. To talk about the instructions on the bottle under such conditions is ridiculous and exploitative. Such talk preyed upon stupidity.
And with Bhopal on the scene talk of justice is laughable. It was a fill your boots job. A carrion fest. With eyes severe.
