The fully trained, but still new to the force rookies held Floyd down while Chavin executed him. They were not passive bystanders. One of the rookies said they should move him, but did not. That rookie was given some leniency for trying to do the right thing, but still convicted because he didn't actually do it.

This asshole stopped a crowd that was begging to help save floyds life, including a paramedic/firefighter that told them Floyd was dying. He then told jokes as floyd choked to death, begging for his mother.

It's all on video, all 9+ minutes. You can watch the whole murder in real time. Go do it if you doubt any of the above.

All 4 officers could have made different and better choices that day, but instead all 4 opted to either murder a man or let a man be murdered. They all got what they deserved.
