Man, that cop wasn't there to break up no fight...
he got out the car, hand on his pistol... when they started fighting literally inches from him, he kept his hand on his pistol instead of attempting to tackle the girl, disarm her, grab her, hold her, ANYTHING OF THE SORT.
You said it best, fam
There's a MULTITUDE of Ls in this video and situation that culminated in the death of that child...
