I actually think that's the case, However knowing that he was a Cardiologist, it makes the case a little bit tricky. You see the delay is inexcusable, medical doctors are under scrutiny because of these type of mistakes...therefore government/universities/hospitals make sure that they know their stuff before letting them work as specialists. A normal CPR could be done by an average Joe, and what happened in MJ's case is totally NOT acceptable. Also combining the drugs is another question mark!! first off he knew that Propofol is used only in theatres by anaesthesiologists, yet he used them on mike, seems Murray was more interested in MJ's cash than health. second mixing BDZs and Propofol is another questionable thing done by a medic. I wouldn't simply put it on him being stupid. He was stupid and greedy at the same time and he has to pay for his doings. MJ was murdered by this guy.
