Attorney Ben Crump makes it clear ... "Warning: This is beyond disturbing, even harder to watch than the first video."

The video which Crump says is new -- maybe a slightly wider angle -- and you see more of Thao, who stands impervious to what is going on right in front of his face. Bystanders are imploring him to do something ... to just look at George Floyd lying on the pavement unconscious and realize he's about to die. But, Thao does nothing.

It's an especially powerful video, because it really underscores a basic problem of law enforcement ... that seniority should have no place when the senior officer crosses the line by brutalizing and killing citizens who pose no threat. Until the culture of the police departments fundamentally change -- where NO DEFERENCE is paid to rogue cops, despite their seniority, and de-escalation and proportionality of force becomes engrained -- these murders will not stop.
