Whilst you rightly point out it is out of control, having just been shown the Tyre Nichols footage by my wife I really wouldn't use the term 'misconduct' to describe what I watched; imo to do so diminishes the gravity of this and other incidents. It is criminal behaviour of the most egregious nature.
This.
It’s murder and they have rightly been charged with such.
Everyone at that scene is culpable, even the medical crew who stood and watched him die.
Charge them all.
