The grieving parents of a 7-year-old child who died hours after being hit by a car were charged with involuntary manslaughter after allowing him and his brother, 10, to walk home unaccompanied by an adult from a nearby grocery store.
On top of what everyone else has said, my stance in general is that anyone who harms another with their car should have their license revoked for at least 5 years if they were at all at fault, which this man certainly was being the driver hitting a pedestrian. On top of that, he's at the age where he should probably stop driving anyway. While I don't exactly believe this warrants jail time, especially if the driver has been as cooperative as they are saying, I do think he needs to be charged with something just to get him off the road for the foreseeable future. Outside of that though I do agree with you.
