"if only they had been compliant" is blaming the murder victim. People are rightly scared of cops, and it's to be expected they will not always act rationally. If police aren't trained to deal with that, and to defuse fear, then they need to be replaced with those who are.
The length of the altercation - 43 minutes - is being used against the 2 officers.
Isn't this what you want - that the duo takes time (see the video) to speak respectfully to the man?
How is "why did this take so long?" an issue here? (see media)
Drag out of car, beat down and cuff is not what you want, after all.
