IMO the cops at fault. Because the officer had stopped the van before like he did, than he knew the kids were inside that van. A cop is trained to assess the situation when first initiates contact with the driver of the car. When a cop pulls someone over and is standing at the window of the vehicle he looks inside the car to see how many are inside, if he smells marijuana, if anything is out of place inside the vehicle. Once that cop saw those kids inside that van than he should have never fired on it period. Is the mother at fault for driving off? Sure she is, but how does that bring as punishment deadly force to innocent passengers in the Van? Another case of police going way to far.
