This is not correct. He was being arrested but he refused to put his hands behind him to be handcuffed. He told the police that they had bothered him enough and it was going to stop now. (you can google the exact quote) That was when the officer went to him and used the choke hold and got him to the ground where officers held him down hard. It was clear that the man was resisting and offering veiled threats but it definitely was different from the other case in that the officers never feared for their lives or were being attacked at any point in this episode.
Right, I have a hard time believing that with the six or so officers on scene they couldn't have gotten a 43 year old obese man against the wall with his hands behind his back. Then once he is on the ground the guy can probably release the choke instead of ignoring the man's constant attempts to tell them he couldn't breathe.
