But prosecutors don't have to prove that Chauvin's actions alone caused Floyd's death, according to Minnesota's guidelines for jury instructions in criminal cases. According to the state and the defense's proposed jury instructions, " 'To cause' means to be a substantial causal factor in causing the death. … The fact that other causes contribute to the death does not relieve the defendant of criminal liability."
Cause of death at issue in Derek Chauvin trial
That's why the legal arguments are so interesting to me in this case.
So far the prosecution has provided witnesses who have testified that IMO:
1) Mr Floyd was not resisting (shortly) after being placed face down.
2) Neck restraint was taught, but not in the manner used by DC
3) Officers are trained/should know to put someone in recovery position after prone restraint.
4) Officers train in CPR.
Defense has poked holes in some of 1-4, IMO. 1-4 are all involved, AFAIK in the reasonableness doctrine of Graham v Connor.
5) Mr Floyd died due to the hypoxia caused by the restraint.
6) Prosecution agrees that cardiomegaly and atherosclerosis of the cardiac arteries were present.
7) Prosecution agrees that fentanyl and methamphetamine (amongst other substances), were found in Mr Floyd's blood.
Prosecution argues that #5 was the substantial causative factor in Mr Floyd's death, and therefore DC is responsible.
Defense has been trying to question that assertion, and I expect they will continue to do so.
What else does the prosecution have to do to prove cause?
What doubts have been raised by the defense so far?
What does the defense have to do to overcome the prosecution's case?
I'm not getting much of anything else done, but I am eagerly awaiting what we will hear next week.
