Truth. If I somehow found myself in that situation with 30 rounds in the magazine... There would have been a lot more bodies in the pile.
Between 3-gun shooting and my time in the Marines... My tactics would be a bit more... robust.
He did show remarkable threat identification and restraint.
After he fled the first shooting and then fell while being chased by a mob, one guy jump kicked him in the head and knocked him back on the ground, the second guy, who hit him with the skateboard, appeares to have tried to take control of the rifle and was shot. The third guy running towards him with what appears to be a small glock (what looks like glock sites can be seen in another picture) in his right hand stopped and put his hands up in surrender, still holding the pistol in his right hand. The kid did not fire at the man holding the pistol until that man appears to have decided to “go for it” and gets shot in the arm holding the pistol.
A fourth man who stopped charging him and froze a few feet away from him was allowed to retreat unharmed.
The kid then gets up and continues towards the police vehicles with his hands up.
