These children got caught in the crossfire. Crossfire is a two way thing.
Maybe the van was loaded with drugs? Maybe it was just carrying illegals.
Is that worth 7 lives? Is it ok for the kids to die if it's about illegals? I don't think so. Maybe for the drugs /sarcasm
It apparently was worth it to the van driver. He made the decision to FLEE! It is his fault that some died along with him, not the pursuit. Your mind is warped.
As an aside, why should more value be placed on "children"? Each person has the same value to God, don't they? You sound like a Dimocrat crying "for the chil'run"...
