Really?
What narratives, specifically, are RIP?
Sure, he seems altered and agitated and non-compliant...as far as the video goes...which ends right as he goes to the ground. Are you saying that the video justifies or excuses kneeling on his neck for 8:46 as we have all seen?
1.) Police brutality
2.) "I can't breath"
3.) Hostile intent of LEO
If you think the knee to the back is the reason he was saying he can't breath, then why was he saying that long before he was ever on the ground?
If you think putting him on the ground was wrong and hostile, then why was he demanding it and worming out of the car to lay on the ground?
It's pretty clear the officers were trying to cut some leeway here and demonstrate patience with someone who appears to be ODing on drugs or has a psychological condition.
If they didn't care they would have stuffed him in the car and closed the doors with him freaking out. Instead they tried to be accommodating with him to get him to calm down.
