I agree that there are times when pedestrians should be more aware of their surroundings, especially when crossing streets, but I really hope you aren't suggesting that these kids are partially to blame for this.  If the children were in the crosswalk when the vehicle turned and then accelerated toward them, what part of their actions was irresponsible? 
Isn't there something stronger than reckless driving that can be applied? The reckless driving definitions I see don't require a collision/crash/accident. This woman crashed into and injured two people.
