The dumb kid shouldn't have been there, nor should he have had a firearm as a minor there.
Pretty difficult to know if the person chasing you was the one who fired the shot, you turn around and you see someone reaching for you. What is your response? A hug? Note that the person chasing you had threatened to kill you.
You are punched from behind, eventually falling down, someone immediately comes after you as you are on the ground, weapon fires - miss.
Next person lunges at you and hits you with a skateboard (Which by definition could be considered deadly force - It does not need to be a standard weapon).
Another person approaches with hands up, with a pistol in hand then motions towards you.
Murderer? No
Idiot? 100%
