I think it's possibly and even likely Michael had used propofol over the years- my guess is when he was touring and could not sleep otherwise. Not sure how much of a "secret" it was-
as (interestingly after he died) several people talked about knowing. Obviously, this is problematic for the people administering it, as I believe, it is to be used only in clinical settings (at least in the US. Possibly, the docs did not have US licenses...not sure) . If AEG's point is to show he used it before, and he was therefor responsible for his own death, I am sure the plaintiffs will point out that Murray has indeed been convicted of manslaughter. It doesn't matter how many times MJ survived using it- he died under Murray's care. So- the question is not if he used propofol (that is clearly a strategy to muddy the water).
As far as addictive substances- to be physiologically "addictive" (or to be a drug leading to dependency) there have to be a development of tolerance (meaning more and more of a substance is needed to achieve the same result) and withdrawal post continuation. So, not every drug can be physiologically "addictive."
However, if the drug leads to a desired psychological effect, psychological dependence can occur. As propofol evokes different effects in different patients, those getting high and happy from it have a higher chance of becoming psychological dependent.
But still- going back to my other point, I hope the jury won't get stuck on that issue. Obviously, per the emails, AEG knew he was psychologically compromised and did exactly nothing. A cardiologist is NOT a psychiatrist. I'm a mental health professional- and according to the symptoms described by Kenny, MJ should have received an emergency evaluation. In California, you do not have to be solely a danger to self or others to have this requested (as in some states). Of course, to do this might have significantly delayed the time table. So their argument that Murray was on post was ridiculous, as psychological evaluation are outside his scope of practice (as is giving CPR, as we found out). Also- the emails sure make it sound as if they regarded Murray on their team. And that they turned a blind eye to what was going on, covering themselves that a doctor was there. A doctor they said they investigated, but did not. So, we shall see what the jury finds.
The paramedic testimony, was just as haunting as the first time.
Interesting that only Marlon is not on the witness list. Guess he stood his ground. Bravo!
