I don't know if the defence is scoring any points as he is jumping from point to point and I have no idea what they are talking about,
I don't think the focusing on the science will have a huge effect on the juries verdict, things like the use of propofol as a sleeping drug outside of hospital setting, his not calling 911, his not mentioning propfol to paramedics or to Drs at the hospital, his getting propofol delivered to his home, trying to sell the idea that MJ self administered things like this will weigh more in the juries deliberations I think
