Was your point not about about failure of the safety of the individual, as stated below?
As someone had already stated, once handcuffed, the safety and well being of the individual becomes law enforcement's responsibility. They failed and need to answer for it.
If someone dies of a drug overdose, can they be kept safe? I think it is THE point.
The burden of proof is on the prosecution to prove beyond all reasonable doubt.
I've watched the raw footage, although some channels do appear very slanted. I linked to one where he outlines the cases for both sides, which I find good.
Jon, a yes or no question, do you beleive the amount of effort used to restrain him necessary?
I don't believe it is a yes or no answer. If you think it is, I could ask you this question for a yes or no answer: "Do you think it is possible for George Floyd to have died from a combination of 90% blocked artery, high levels of fentanyl in his system and a struggle with police officers?" If you think that is reasonably possible, he is not guilty.
Instead of yes or no, I can give an opinion. George Floyd was 6'5" and 223lbs. Chauvin was 5'9" and 140lbs. That is a huge disparity in size and weight. Add in that Floyd was very muscular, that one of the prosecutions witnesses said the drugs he was on could give superhuman strength and the fact that 3 officers could not successfully keep him in the back of the squad car, despite being handcuffed. He was also not compliant.
Given the above, Floyd was a perceived danger to the police officers. They have first-hand experience to his size and strength, unlike us bystanders. Under those circumstances, what is deemed the correct amount of force? I don't know. Police witnesses have said that restraint techniques can look ugly to viewers, but they may be necessary. Chauvin could have tasered Floyd because he was fighting with the police officers. That would have also looked ugly. But ugly looking methods does not necessarily make the officer using them guilty of murder or manslaughter.
The law doesn't require that Chauvin needs to have acted in a manner that with 20:20 hindsight might be viewed differently. Several times, a particular court case was brought up by both sides covering this point. You have to factor in the reasonable police officers own perspective and bear in mind they are making spilt second decisions with imperfect information under dynamic evolving conditions. I do my best to make the best code I can, but it is littered with bugs. Human error comes built in.
In essence, to answer your question in the briefest terms (after a long monolog!), I don't know. But because I don't know, that is another factor towards reasonable doubt.
And, if he was already dying from a drug overdose, excessive restraint may be an irrelevance to the outcome. I believe they use a "but-for" causation criteria. "But-for Chauvin's actions, would Floyd have died anyway?" If not, Chauvin was the cause.
To prove causation, the prosecution must show "but-for" causation and reasonable foreseeability.

Edit: As a side note, Chauvin worked in security at a nightclub at the same time as Floyd. What if he knew of his violent criminal history and prison time, and the fact he was a bouncer, possibly with trained techniques in combat? Could that go into Chauvin's decision making if he recognised him? Perhaps the defence will flesh this out this coming week.
