I do believe if any of the witnesses/participants with the restraint "approved" of Neely's death, they would have been charged. I think their agenda was subdue and protect JN as well as his intended victims.

All of which (subdue and protect) could have been done without a lethal chokehold.
ETA: We do not know if Mr Neely had ANY “intended victims” or if he was just on a rant. Witnesses will tell us that when they testify.
