If this was gang related, and this man brought the attack on his own family, then started shooting down a crowded street at his enemies...
Consider if your family were walking down the same street he was spraying, all as part of gang activity.
A crowded street in Texas, where a man has a woman in a headlock and he and his pard are dragging her and her kid off, and none of those witnesses/bystanders tries to help the woman and kid?
Not in the corner of Texas where I lived and worked for the better part of a decade.
