I haven't watched it, just done a lot of reading that reported on it. A lot of incriminating evidence so far, for sure.
To me the most interesting aspects of the whole affair have more to do with the other officers' trials - especially the one that was a new hire, and essentially doing what he was told. That, and, which charge(s) are ultimately supported - second-degree unintentional murder, third-degree murder and second-degree manslaughter, etc.
Another thing to note is that, like many criminal cases, we (the public) pretty much knows the prosecution's case. I doubt that there will be much there that everyone doesn't already know, or partially know. The video, Chauvin's responses & phone call, his training, etc.
So to me the more interesting part comes in the defense portion. So far I am hearing a lot about different camera angles showing the knee not actually on the neck much of the time. I expect to hear a lot about: 1) Floyd's previous history of quickly ingesting substances during an arrest and saying he couldn't breathe, and 2) his body's then-current status with regard to drugs.
Lastly, I'll be curious to see whether or not the judge's refusal to grant a change of venue ends up being any solid ground for an appeal or not.
It will be interesting to learn how they approach all these issues. Will be long, I'm sure.
