Here is a thread of the discussion I've had with /u/AXXA today:

TL DR:

It will be important for his attornies to show medical research on the specific amounts of drugs at issue in the present case and in other examples where death can be caused by that specific amount of the drugs in the system of a person with George's level of arteriosclerotic and hypertensive heart disease. The rate of absorption into George's system should also be considered. If all of that technical evidence is appropriately presented, Chauvin could walk (with probation) with a reckless endangerment conviction (and it will likely cause riots, but that's not really at issue here). The Special Assistant Attorney General Jerry Blackwell will now push for the argument that Chauvin "betrayed the badge", which seems like he's backing away from the murder charge, if I read this correctly. Thus if the A.G. fails to do his best work, Chauvin won't spend a day in jail. The time it takes to absorb the drugs George took, along with other drug and health factors, followed by Chauvin leaning on George's neck for 9 minutes, still seems to indicate that the most immediate cause of death was suffocation, per the medpagetoday.com link above.
