questions should be asked about what could have been done to prevent that tragedy.

A child who does not understand that the orange tip on a replica pistol is there to save your life is too young to be allowed to own a replica pistol. A child who does not understand that the appropriate response to a police officer telling you to put your hands in the air is not to draw your replica pistol modified to look like a deadly weapon is also too young to be allowed to own a replica pistol. Preventing the tragedy is simple: his parents needed to be parents, and not let him do something incredibly dangerous until he was old enough to manage the risk.
