Best summary so far:

Teens steal jeep inside CHAZ and do donuts in the field for fun. Windows closed the entire time
Chaz security fires at car
Everyone panics at gunfire, screeching White woman tells everyone who's armed to get on deck.
Teens try to flee, but can't because the whole thing is blocked off with jersey barriers placed there by the city.
Car zips around through the maze of jersey barriers but can't get out. At some point they head toward the CHAZ HQ, not even knowing that it was a thing.
Chaz security shoots through the window of car, driver crashes into barrier near front of the HQ.
They unload more bullets into the car and make it Swiss-Cheese.
Car is no longer drivable, two teenagers are now bleeding out.
Eric Leal, the self-styled "security Chief" of CHAZ still thinks they were enemy forces of some sort. Says, "Oh, you aren't dead yet, huh?" and then pistol whips the living guy for about a minute and then shoots him execution style.
No weapons in the car. Literally CHAZ has murdered an UNARMED, BLACK CHILD brutally, and judging by the giggles heard in the background of one of the videos, with glee. They have already become the pigs that they thought they were fighting against. CHAZ wall of silence in effect. "No snitching".
