Seriously. Do you think that if a bunch of white kids had driven into the guy's driveway he'd still have come out waving a gun and shooting?
You could tell the kid was Colombian by looking at him, or even Hispanic?
And what do you know about the race of the other kids in the car? It's not even mentioned. It may well have been a "bunch of white kids".
eta: I see several of the quoted passengers have Hispanic names, but there's no indication that Sailor knew the race of the people in the car.
Kind of hard to determine that at night when the windows are rolled up.
