When your child accidentally kills another child.

An 8-year-old boy in NYC caused the death of an 8 year-old girl. He got into an unattended school bus and released the parking brake. As a parent, you think about how you would feel if your child died, but not so much how you would feel and what you would do if your child killed someone else. You don't picture your child becoming a murderer, but you may not think of how easy it would be for a little child to kill another child by accident. How would you go about being a good parent to your child after that happened?
