Yeah, that was people with some training, not your average hood shooters. exit, shooting stance, shoot, move, shoot, work as a team. If you watch closely, you'll see the driver raising his muzzle only to have passenger start crossing his line of fire, which causes him to briefly point his muzzle back down before bringing it up again to fire. Compare that to countless videos of chicago hood shooters doing wild one handed shooting while running, hitting everything but the person they're aiming for
With the lighter skin you can just barely see between the mask and hoodie, I'm guessing it has something to do with central/south american military trained gang members.
The area in question, if it matters
Also, that's only a mile from where my ex did her grad school. I've walked around some of that area.
